Love the Shyvana buffs on PBE! BUT..
Current changes (skip past the line at the bottom for the real reason I'm posting);

1 - Fury of the Dragonborn (Passive) "Shyvana passive now gains a stack with Elder Dragon " "Cloud Dragon now increases fury gains on Shyvana by the same amount of Ult CDR it grants (cause her ult has no actual cooldown)"
2 - Flame Breath (E) On Hit Damage increased from 3.25% Max Health to 3.75% Max Health Monster damage cap increased from 100 to 150
Awesome little buff. Despite what people say about AP Shyvana she is easily countered by
(for the burn effect) and
, all the standard items for dealing with burst champions. I greatly appreciate you not locking her into her AD/Bruiser build, Riot. Shyvana has no cc and is a champion that needs to be adaptable with her builds because her items are where her team contribution comes from.
The main thing I want to address is the Air Dragon buff to her Rage bar. This is a great change in concept, however what if there is no Air dragon that spawns that game? Shyvana might be fantastic at soloing dragons but there is also the matter of enemy team grouping, enemy jungler movements, the current meta favoring early grouping and team fighting bot side and in the bot jungle to secure the dragons. The nerfs to the dragons this patch might help alleviate SOME pressure to "need to get every dragon", but the dragon souls being in the game will always trump any nerfs to the buffs themselves given that it's a permanent team buff.
Shyvana simply needs to replenish rage while she's respawning. The Air dragon changes to her is as close to an open acknowledgement that this needed to happen for a long time imo. Simply allow her to regain her resource while respawning. Shyvana is in amazing spot right now for what she is. Her numbers are great, her itemization is great, her drawbacks and strengths are clearly defined, yet having to go into the jungle just to recharge your ult while your team rages at you for preparing for the next fight, has been asinine for a long time. Forget the Air dragon change and just make the change you know needs to be made and nothing else and you will have a perfectly balanced champion for once.
