I'll definitely have to agree with the fact that some of the new reporting schemes are really off. Don't get me wrong however, I really like how the new reporting system works and how divided it is. It brings a greater light (when reports are necessary) to what was going on without having to write out an entire paragraph explaining what was happening. I especially like the distinctions for intentional feeding, refusing to communicate, and spamming because those are never fun to deal with.
But when it comes to some of the other new ones (e.g. Unskilled Player and Negative Attitude), I really don't see why these are reasons for reporting. Yes I know that bans based on reports are not automatic, but these topics for reporting are so subjective that any player could be subject to report. Maybe they are communicating with their team but they are annoyed and it comes out in their messages. It doesn't hinder the game, but with the new system they could be subject to reports. It might not even be that bad either. Maybe they're trying out a new champion or a champion they aren't so great with. If they have a bad game they could be reported for being "unskilled." It seems so biased based on how the game is going. Lanemates and team communication usually play a larger part in the kill/death/assist ratios than actual skill (in my experience).
So If I had to make my point concise, I would say that the report options should be kept objective rather than the subjectivity of a report-happy player base.
