balance through Balance

I do not think that with the Balance nerf they should bump AST's personal DPS. AST would still be bringing an assumed 10% damage bump to the party. That is more than satisfactory.

To be clear: if the AST uses Balance on the party, then it is a 10% increase to outgoing damage for all party members in range of the target (unless an enemy is targeted, in which case, the user is the epicenter) for 30 seconds (where either the Ewer or the Spire must be used for Royal Road).
If it is single target, it is either 20% increase to outgoing damage for 30-60 seconds (depending if either the Arrow or the Spear were used for Royal Road, or if the Balance is used raw) or a 30% increase to outgoing damage for 30 seconds (if either the Bole or the Balance is used for Royal Road).

So if you meant what you said with regards to party buffing, then we're already there.
If you're saying to reduce the potency back to what it was, then halve each of the increases (but not the time limit increases) and we'll be back to where we were before Balance/Bole/Ewer/Spire were buffed.
Incidentally, it's also important to keep in mind that this does not increase attack magic or attack skill potency, as, say, Cleric Stance does. It's still an increase in damage, obviously, but the calculation seems to be different (in my experience, 10% increase from Balance is just a little teeny bit stronger than Cleric stance, basically granting about a rounded up 100 damage more on my lowest and highest hits with the 10% damage increase from balance than the 5% potency increase from Cleric stance, so take that as you will).

Also, @Supersun, I would imagine the reason why Berserk wasn't given to WHM, is because WAR has it as a personal ability. As for Haste, I have no idea.
