I love the people complaining about Rengar
Now that he has windows to actually react to him. I'm sorry, but I didn't hate Rengar too much before. I will still say the changes didn't really even effect him that much. The new range on his ult warning gives you about .5-1s extra warning and now he can't just drop his entire burst on you while he is in the air. You actually go "Oh there's a Rengar on me, it's time for me to juke to hopefully dodge 1/5 his damage". It just makes Rengar take more skill, his damage is near identical. I'm sorry that now when you are 6, you no longer instant gib any squishy in your path.
I never really had problems with Rengar before (he could be pretty infuriating, but I never let him get as out of hand as he is made out to be). I mean I play crit Rengar for fun and that is pretty damn toxic. You think him jumping on you for 2k damage was broken. Imagine him jumping on you for 3k+ and then having his DPS up immediately afterwards instead of like 4s later.
