I don't mind the auto switching, its quite nice, especially for weapons like the Zenistar which is so much better for deploying the disk.
but there should be some option to "opt-out" of the fully equipped stance for the melee.
Polearms are my big example, I HATE, no DETEST, the equipped stance animations.
They are horribly slow and ruin the game.
Un-equipping the stance mod makes it worse (you'd think it would revert to how the quick melee worked, but no)
Having built like 13 different polearms I now really hate them all.
At this point I basically stopped using melee except in rare cases and just carry my Zenistar for choke points.
NEED TO FIX.
