Garthanos
Arcadian Knight
Meh, one does thunder damage, one does psychic. One puts out a pretty decent amount of damage, the other doesn't. One targets FORT and one targets WILL. They are, to some extent, useful for different things. I tend to agree that BS is a bit of a spoiler power, being party friendly and just generally being obviously simple to employ. The damage output of T-Wave isn't ENOUGH more to have a vast impact, etc.
The difference in Area and combined with ally friendly is pretty damn huge... And I let people thematically re-damage type things all the time.
It takes an incredibly narrow build for it to even be halfway viable.If you're going to build in that direction ANYWAY, then this is a fairly smart power to have.
