They don't remove PvP power, as if they did, we would all go full PvE. Also only base resilience is higher, but resilience gets stripped off of (most) gear. So Burst isn't under control, no.Burst is meant to be addressed via Resilience. The problem is they added PvP Power, so any mitigation provided by Resilience was lost, and burst was back to its ridiculous levels. With the upcoming patch, higher base resilience, and next to no PvP Power, burst should be be under control. No need for counter-intuitive mechanisms
Only concern would be that healing might become too powerful (as it happened in prior expansions as Resilience went up) but at least this time they have Battle Fatigue to fine-tune that.
Also healing get's nerfed opposed to how it is on live.
