In the past I've suggest that we simply change the name of Take Aim to Call Down The Thunder.
I've got a better idea. Make a new skill with that name and let it only be used on people who you have 0 IP against. Have it grant you, oh I dunno, 10 IP? Give it a decently sized cooldown (about the same length as cleave should be good enough) after use and then let people get on with battle early on instead of going through the boring coin stacking part.
Take Aim will obviously still be mandatory even if this is added.
