In 3 and half years I don't think I've ever even used the Dip mechanic. It was the first icon I removed from the hotbar when I ran out of space trying to for go a tripleclass spellcasting character, followed by improvised weapon which I also never used. This wasn't like trying to self nerf, I just never found myself using it, so it was the first thing on the chop chop block.
I think it's silly, the whole idea of coating our metal weapons in corrosive acids, or sticking my sword in live wire electricity, or lighting it on fire, certainly not with a candle lol. Just like Lae'zel, I balk at candles in this game! But honestly none of those are the reason I didn't really use dip - I didn't dip it because I found it perpetually inconvenient in the moment. Like trying to walk up to the edge of a poison puddle to dip an arrow or whatever, it just always seems like a wasted movement to do it spontaneously, and again, too silly to do it with purpose.
Excellent idea. As I never dip ('cause it is so silly my mind refises to remember this :)) this is icon will get the boot.
Improvised weapons probably too.
Maybe some day I will play a cuttlery throwing themed Barbarian - only then I'd remember about imrpvised thingies.
