As long as my main is not ARC, I'll ask you pro folks:

Why the ARC limit break skill is a sub-rate heal? I'm used to think that LB is an awesome skill to use at the right moment, but when I used it first time, it was to me... lolwut?!

As long as I am in party with DPS role, I were expecting a DPS skill, and a powerful one, too.
But it was a circle heal, and also of sub-rate power. I ruined everyone's else LB.
But maybe later it will prove useful, let me know please!
