Balance Proposal: Winterwitch

[RadicalX]

 Winterwitch

• Card Changes

Hp: 1350 -> 1700
Shield value: 1500 -> 2000
Ability power costs: 100 -> 65 

Winterwitch lacks power that makes her worthy for a T4 card that demands 3 Frost orbs. The biggest current issues we see with this card are the low survivability in a T4 environment & the nonexistent synergy with AoE damage reductions. Cards like Ward of the North or Revenge have no effect onto iceshields. Therefore we want to increase her supportive strengh. 

Chosen card changes: 
The hp buff mainly is supposed to increase her survivability to get a proper positioning and good shield area placement. Regarding her ability a shield increase of 500 seems to be a low amount, but as Winterwitch provides up to 15 shields therefore it stacks up. An ability cost reduction is supposed to help players that have no access to voidmanipulation, which isn't guaranteed in a triple Frost deck.
