only useful for pubs...in gm duels, anyone good will have plenty of stack available, making your damage terrible.
not only that, but you suggest using Lo griffs + tgods versus light characters, so you're bming...which means the other guy is free to strap on max stack + 2 wisps + tgods and turn your asshole inside out.
FoH are garbage characters outside of pubs, and that's pretty much the bottom line. i'm sorry you've wasted 1.5 years on them, go pick a real dueler now and start over imo.
