I was speaking for the purpose of defense, maybe its just the way I play rune, but lunge/gambit seem unnecessary, I tend to forget they're even there lol, of course that being said I've never had defensive issues on rune ether, the few times I've done content on it anyway, although when you need to switch rune it is a bit time consuming, I wish they would change the rune enhancement merit back so it reduced recast to 0, that would take the edge off of it, and since runes don't make enmity now anyway its not like spamming them back to back would be particularly OP
I didn't mean to sound like I was disregarding your idea, I was just trying to make sure I was understanding your intention correctly
