I saw the pbe changes. Are you trying to kill taliyah?
Threaded Volley (Q)
Mana cost lowered from 60/70/80/90/100 to 50/60/70/80/90
Worked ground duration lowered from 120 seconds to 45 seconds
Cooldown lowered from 11/9/7/5/3 to 7/6/5/4/3
Effect now notes "subsequent hits on the same enemy deal 50% reduced damage"
OK riot, so you are planning to remove taliyah from jungle, fine. However you are basically killing taliyah mid at the same time. 50% reduced damage to enemies include MINIONS, that means you require 2 "new" Qs to deal the same damage to a wave instead of 1 "old" Q, WHICH MEANS IT REQUIRES MORE TIME TO PUSH AND THAT THE LOWER MANA COST DOESNT MATTER BECAUSE YOU STILL END UP USING MORE MANA TO PUSH.
Now some may suggest buying tear, use all the mana runes, and go for late game. The problem with that is that taliyah is not a good scaling champion and relies on roaming, early game pressure and snowballing the team which she has already struggled to do since the TWT nerfs and will struggle even more if the pbe nerfs go live.
+ Blue buff, all the AP you can get from the new runes, and extra damage from dematerializer, a full 5-rock Q can't kill a melee creep.
If you want any kind of wave clear, you either have to E+W, or use multiple Qs spread out over as much of a wave as possible.
has a great kit and would be a pity to see her overnerfed. She's fairly skill-based and has some good counterplay patterns. I've also got no problem with her jungling, it's a nice change to the usual Graves, Lee, Xin jungle.
