Yeah I hear you Ace, I've had to toss a few 58 gr keys for forgetting to swap skills on my barb which hurts like a bitch. I only have time to farm trials one or two times a week at this point. The issue of time goes to moot if you're ok with times to rg and you generally have more fun with the FoTH setups, you have to actually enjoy what you're farming with otherwise..urge to log... XD.
If you want to add some punch, I'd suggest harrignton waistguard for chests, if I remember right using the "fervor" passive you have the available cdr for perm AC without needing a Vig belt. Between that and F/R or SOJ/Convention you should find that you move along quite well. Happy zapping XD.
