In PvP, enhance has had the ability to cast back to back instant healing surges since legion when we lost sham rage.
We don’t have that anymore with overflowing.
Consider buffing 5 stack and nerfing overflowing in PvP to bring back 5 stack play. Being able to bank 2 heals or 1 while casting is an important safety net for enhance that we have lost with overflowing.
Alternatively, make overflowing increase max stacks to 15 so we can still bank and avoid overcapping. 5 stack casts vs 10 stack cap was such a great evolution for enhance and overflowing ruined it and is a major step backwards for the spec.
Another option would be to turn overflowing into a choice node with an alternative choice to enhance the power of 5 stack casts instead of increasing consumption to 10 stack. Then 10 stack could still be used in high target count environments with high/consistent MSW generation and enhanced 5 stack could be used for single target/pvp other low MSW generating scenarios. Could help balance out the power of MSW stack casts across different target count scenarios.
Also, please consider reducing the impact of dampening on DPS specs. Dampening destroys the ability of hybrids to survive and to contribute a major source of their utility. Double DPS 2s teams are already subject to lighter dampening rules. How about extending that type of treatment to DPS specs in all forms of PvP?
