That's just the Jungle cycle though: Jungle too hard, nobody wants the role, nerf jungle, real or new junglers start steamrolling it, nerf those champs, unintended champs start jungling, buff jungle, champ you bought as a rare AP jungler has now been completely gutted (and they ruined her spider form dance animation to boot).
That's just little gripes about a huge system. The Renekton stuff is what really bugs me as just a huge inconsistency compared to other on-hit abilities or fury systems. I'd love to play nothing but Renekton on my main account, but every time I do there's always that naggy shit about him that got ignored when they remodeled him just a month or whatever ago. "This next swing will give me 50 fury, but I can't hit my ability immediately, I have to wait for the stupid meter to actually show i have 50 fury" or "Okay wait, I used W, saw Ren start to swing at that minion, my W got used, but the minion died and I didn't get the gold, wtf?".
