i did a bit of limit break damage testing.

Assuming your tests were accurate, that's not surprising.

Melee is single target. It should do a lot more.

Ranged is a very long line, capable of hitting more mobs than the Mage limit break if positioned correctly.

So...nothing to see here?

In practice it shouldn't be possible to hit more mobs than the Mage since they will all be clumped in a circle in front of the tank. There have been rare occasions where the stars have aligned and I manage to hit 4 mobs in a row where a mage could only hit two, but I'm assuming the reduced potency is due to the fact that it's impossible (I think) to miss your main target since it's a targeted skill (not a placed aoe).
