The Riven ult buffs backfired A LOT
The increase of damage on Riven's ult made it through the PBE, even though the community had a VERY strong distaste about it, now that you changed it so basic attacks could be canceled VERY FEW frames earlier, Riven Fast combo is (arguably) harder to pull off, but is a decent amount faster. This gives her more burst, which is something the ult changes already did. Now she can easily 100-0 squishies without even the use of her ult at 20 minutes, and with black clear, which (imo) is core, can easily get all stacks and 100-0 tanks at a little slower speed.
Too much burst!!!
And for all of you who will say that I am just salty, Riven is my second most played champion. dirty riven main



(this one is meh, adc's dont have any targeted hard CC -_-)
