Shyvana's kit has been a mess because of Devourer

Riot should really take a look at her kit because Devourer really messed things up for her (good and bad). This is what has happened since the height of Devourer.

1. Jungle Shyvana was way too strong but things like titanic were nerfed to slow how fast champions could clear camps/minions (as well as no longer getting the fast 5 rift herald stacks). Top lane Shyvana was subpar. Shyvana continued to be way too strong in the jungle despite making getting sated more difficult and needed to be nerfed.

2. Twin bite was nerfed to slow down her early game/dueling. This was an especially hard nerf as most people would level this up last but this change made it difficult to trade without leveling it after burnout. Thus, it had multiple effects on her gameplay and also made top lane Shyvana very weak (she is currently at 38% for the few people that attempt to play her there). People rightfully began to wonder if she was being Sejuanied.

3. Devourer was removed and Shyvana was given AP ratios on burnout to make buying Guinsoos a solid part of her kit. However, in practice this item turned out to be less than ideal. Most players skip buying it and just allow all the AP on her kit to go to waste. Jungle Shyvana is currently only played at roughly a 2.8% play rate as there are better options at the moment. This recent patch she was able to climb back over the 50% win rate mark but I assume it is only because her play rate has gotten so small that win rates aren't as accurate.

I would suggest removing the AP ratio on her burnout as very few people are actually trying to use them. Then taking a look at twin bite again and improving it to a point where the ability doesn't feel terrible (whether that be through damage buffs, adding a slow, consuming the flame breath mark for damage, etc.) I would say to simply revert the Q nerf but I have been around long enough to know that nothing ever gets reverted in league of legends for some bizarre reason.
