I've noticed this as well. Even I'm doing more or equal DPS on my AST on average since 4.3, and I'm nowhere near as comfortable on AST as I am on WHM. Not even taking into consideration the raid DPS they add...

As already mentioned, it's just a tad bit too early to panic now, but this is extremely concerning. SCH was already beating WHM in personal DPS, and now AST may be as well. So where is this leaving WHM? This is really starting to look like 3.4 all over again, except it's slightly better because at least WHM has better MP management this time around.

I know that SE, for whatever reason, doesn't like buffing WHM damage, but I think it really needs it at this point. It shouldn't be losing to AST and SCH in personal DPS at all.
