Is there one that actually tells you why one champ counters another? Otherwise they seem rather useless, because sometimes I cannot tell on my own what makes one champ good over another. For example, Warwick counters Gragas, but as a Warwick main, I have no idea how to abuse that WR difference. I assume I have a faster clear, but how would I abuse pathing and whatnot to absolutely wreck his day?
The ones I know of base it off stats collected from match history. So they would not really have a good answer to give even if they tried.
But honestly, counters only exist when people play correctly. You, me, and the majority of players are not at a a level where such is usually the case.
Instead of worrying about counters, focus on improving at the game basics. For jungle, learn to clear/path efficiently. Learn to look at lanes as you farm and get good at predicting if the lane will play out such that a good gank opprotunity will come up. Learn to predict where the enemy jungler could be without needing constant vision of them to do so.
In the case of Warwick vs Gragas, I don't think it is so much a counter pick as it is that Gragas is just not in a very good spot right now while Warwick is fairly strong after his Q and W buffs. Gragas in particular only does well in 2 matchups which are Sejuani and Malphite. The win rate difference is just because Warwick is currently stronger so there is no need to overthink it. Just play the game as you normally do and you should outperform.
