Simply, what do want to see in BFA in regards for gear and weapon effects?
I, personally, am quite alright with effects but feel it could be toned down a little with faction-styled gear and weapons.
I am especially a bit tired on things such as smoke or glowing coming out of every weapon or shoulder armor since TBC. It is a bit tiresome looking like a walking furnace now and then and having a weapon that looks like you could take a smoke puff from it as well.
