Win or lose, Cassiopeia is less enjoyable since the last set of balance changes

I know Riot wants to push her towards the lategame AP-oriented build because of mask abusers, and no doubt she's an even bigger lategame threat now,

BUT THERE IS NO LATE GAME

By the time I get enough AP to break even with the previous power level, the game is over. It's so hard to do anything with her right now because everyone hits too hard early, and by everyone I mean ADCs. Cassiopeia needs 250AP to reach the same power level as before, 250AP is at least 2.5-3 items. (You really have to bear in mind that and take time to stack. They aren't instant power spikes) Meanwhile ADC's start destroying with

Not asking for huge buffs, just slight re-adjustment of power again. Because right now, she takes so long to become useful it's pointless picking her.

Current patch 7.18:

Twin Fangs BONUS DAMAGE VS POISONED TARGETS 15/40/65/90/115 ⇒10/30/50/70/90 BONUS RATIO VS POISONED TARGETS 0.4 ability power ⇒ 0.5 ability power

You need 250 AP to reach the same damage potential as before

Change it to

BONUS DAMAGE VS POISONED TARGETS Level 5 E: 115 ⇒95 BONUS RATIO VS POISONED TARGETS 0.4 ability power ⇒ 0.5 ability power

Now you only need 200 AP to break even. Seems fair riot?

Honestly, this wouldn't even be a problem if it weren't for the ADC dictating every single game. You pick Cassiopeia as a damage threat and she is taking too long to be of any use. Other mages offer reliable utility and can still be useful without relying too much on heavy damage.
