Double barrel is antisupport gem on early game

it's not helping, 3o% less actually 60% less reload speed as i feel.
I feel myself a r&&&rd when equip this support gem, i don't get upgrade, i slower than when i just shot and reload 1 ammo with base character. And this just remind that ggg still didn't make auto reload when switching ammo, need tap 2 times which is annoying af, especially when i play with double barrel, and i feel myself r@@@rd when equip this supp gem. Game already too slow(after poe1 it's torture for me actually, imagine sprint only after roll..)
