I think he means:
If a sws songs Hunter , Earth, Wind, the next song will always cost more, but if you restart even if you have 4 songs on, if you keep singing the skills will start again from mp base 60, at least i abused this on many servers and worked liks this.
Yep i know, but maybe the Dominator and the Mages who spell force him are behind all the mass but enough in range to get the skill over the head (Already happened with Titans) , specially to start hitting just when FoI ends.
