Don't get me wrong, I'm not complaining - it's a very welcome change.
It just feels kind of pointless for group play?
The way I use the move is not any different from how I used to used to apply, I always select a target(often a healer or anothertank) as usual.
Was it adjusted for solo applications?
It definitely makes a difference there is that is the case.
WAR is now my defacto solo play tank, ahead of even PLD now.
