So, forgive me if I'm not seeing something here, but this a 5% physical dmg only AOE buff, that lasts 15 seconds, doesn't effect the user of the skill, and has a CHANCE to give you chakra per weaponskill (not attacks, weapon skill. Very important distinction).

Why is this thing so weak? This is more useless than 3.0 AST AOE balance on release. At least that effected everyone, mages and physical attackers alike.

Even if you're extremely lucky with RNG and you get a chakra every second, that's at most 2 FCs considering it's CD.
And why can't we at least be effected by the damage buff as well? DRG is effected by Battle Litany, NIN can benefit from Trick Attack. What's up with this? It feels so weak and undertuned.
