In my personal opinion, note opinion, STSF is one of the lamest overly used legacies. I personally think it retarded the amount of ability that it gives a warrior over so many other legacies, that and the fact it's fairly similar to martial trance. Which again is stupid and the large advantage it gives the warrior over certain classes, with almost no repercussions against a warrior.

I personally think that charges should

A. Accumulate at a FAR slower rate as the helpful suggests it is for multiple combat with foes, not 8-10 round I win.

B. Lower the variety of abilities. Giving a warrior cut off seems redundant with the amount of lagging ability.

C. Be removed entirely. Can argue all night long about this one, but the game would be better off if the legacy was scrapped.
Note I also mean one or the other, not all of these.
