I'm really not convinced on walking casts for pve (hint: they're worse to play around than actual casts, way more cumbersome to cancel, and won't magically make you able to dodge stuff much easier, but they do feel less stressful to use).

But I do believe that pve design could definitely take inspiration from a lot of pvp concepts. What feels great with pvp MCH is the burst flexibility and how to set it up, and how to end it. You end up making choices every 20s with wildfire that all adjust to the situation, where the target stands, etc. I wish the job was more focused on those small regular and modular bursts than the current carpal tunnel spamm of pve hypercharge.

What pvp MCH does badly though is overheat, which is frankly, not very great and controllable. I hope they do change it for 7.1. Ironically overheat burst was great in pve...
