Review Detail of Sevnir in Parasyte System

I've read 91 chapters. Love the idea. Hate the execution and pace. The development is sooo ssllooowww, and the horrible update schedule just makes it worse. I don't expect him to be a god among men by now, but a system should provide more growth at a faster rate. After nearly 100 chapters, Jay still seems weak. When compared to other similar novels, the progress is much more tangible in every other novel I've seen. He has basically only used his system powers THREE times in 91 chapters! Also, the powers he does obtain with the system seem to grow at the normal rate of needing YEARS of honing. Then there is the issue of making small advances seem huge. Jay can now mildly sense what his parasites feel which gives him a low-powered danger warning sense and the ability to sense the strength of opponents. He can also slightly buff or very mildly influence someone infected with his parasites. He basically has 3 very normal protagonist skills. The author acts like these are insane gains in ability when they're really bland. In 91 chapters, he should have used his system multiple times, should have several skills, and should have tangible growth. The author may as well have left the system and parasites out at this rate, and just made the novel about a guy with 3 normal abilities instead of the usual one per person.
