Frankly from my experience it wasn't that bad on BLM either, though i will say that once I saw V3S and V4s I told myself that ranged were gonna be a thing again.

I doubt that they will allow us to have f1 and b1 instant under enochian though and as for stacking procs, well that was a request of some ppl since 2.0 so not getting my hopes up.

Personally I'd rather have enochian upgrading F1 into F4 and B1 into B4, mostly for a cool factor and a less keybinding factor thinking also to the future, ofc they would refresh stances and procs firestarter.
