During certain events, League of Legends would provide a free experience for all heroes, but under normal circumstances, all heroes in League of Legends were not free. This was because League of Legends adopted a payment mechanism, in which players needed to buy heroes to unlock them. This mechanism helped the game's profits and helped novice players avoid making difficult choices among many heroes. Therefore, although all heroes could be experienced for free in certain events, under normal circumstances, the heroes in League of Legends were not all free.

I'm not sure what you want to know about the free substitute players in League of Legends. Can you provide more context or background information so that I can better answer your question?
In League of Legends, newbies could choose a free skin from Eich, Galen, and Robot after completing the novice quest.

Teemo's vision score was high. He could use his own visual field to expose the enemy to obtain vision points. However, the points obtained in this way would not increase too much because the hero spent most of the time online. In addition, he could also use eye positions to achieve vision points. After purchasing accessories, he would insert his eyes in the grass or corners. When the enemy passed by the eye position in the dark area, it would expose the position, thus providing vision to the player. Ai Xi had the ability to detect vision, which also helped the team obtain information about vision. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
In League of Legends, there were some heroes that were relatively difficult to kill. For example, the Enchantress had A bad feeling when she was in the middle of an attack and did not deal enough damage to the minions, so it was difficult for her to replenish the minions. The Scarecrow had a high mana consumption and slow attack speed when she was in the middle of an attack, so it was easy for her to miss the minions. Although Annie could use her skills to attack in an area of effect and could summon a bear to fight, she was often complained by players about replenishing the minions. Parker's skills focused on controlling the enemy hero, so it was difficult for him to replenish the minions. Star Mother and Icebird had low attack power, slow hand lift, and slow attack speed. It was difficult to rely on normal attacks to replenish minions in the early stages. There were also many restrictions to relying on skills to replenish minions. For example, Icebird's E-skill consumed a lot of mana and had no mana regeneration effect. Star Mother's Q-skill had low damage and no effective mana regeneration method. Swein's hand lift was slow and had low attack. In the past, most of his skills were continuous damage skills. Netizens said that it was difficult to even use 50 attacks in 10 minutes. However, Q-skill replenishment was relatively more comfortable and could also consume enemies. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Morgana, Annie, Bullhead, and Ashe were the earliest heroes in League of Legends. In the early stages of the game, Morgana was like a child. Now that she had grown up, she was performing well in the support role. Her E skill was considered a godly skill, and her Q skill had the imprisonment effect. Annie was one of the earliest heroes. She had been a violent mid-laner mage for many years. Her first model was not harmonious, and now her model gave people the feeling of a loli with some cute skin. Although the Ox Head had undergone a revision, it had always been very popular in the support position. It had strong control and team formation abilities, and could withstand more damage in team battles. Moreover, the difference between the first generation and the current model was not much. Ashe was the first hero that many players came into contact with in League of Legends. It was easy to get started but difficult to master, and it required a lot of positioning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The hero positions in League of Legends were divided into Top, Jungler, Mid, AD Carry, and Support. Top was the frontline position of the battle. They usually chose a tank-type hero or a high-explosive killer-type hero. They were responsible for gaining an advantage in the early stages of the game and maintaining their dominant position in the line. At the same time, they used towers and wild monsters to increase their advantage in the line. In the early stages of the game, they fought against their opponents and maintained the pressure in the line to help the team gain an advantage in other areas of the map. The Jungler was responsible for controlling the map's resources and choosing champions with good wilderness clearing abilities. He had to make full use of the map's strategic points to help the team gain an advantage, and he also had to provide support to the players in other locations. Mid laners were one of the core characters of the team. They would choose champions with high explosive power and survivability to deal damage and control the situation, ensuring their damage output and survivability in team battles. AD Carry was one of the main damage output characters of the team. It was usually a long-range physical damage output hero. It was most useful in the later stages of the game. The team needed to protect its survival and ensure that it received enough money and experience. The Support was the protective role in the team. Choose heroes with control skills and replenishment abilities to protect the survival of AD Carry, control the battle situation, and provide a larger field of vision for the team. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
