Can someone give me an in-depth explanation why Summoner is arguably the worst DPS?

It makes a difference, yes. Quite noticable. But it's not enough and I sure as hell hope SE feels the same. Still disgusted by the lack of trying? It's very disappointing. But who knows. Once SMN can actually bring to the table, the same a BLM can do, in one way or another, I'll come back to it.

Called it, smn is functional with the exception of mp issues (and works well in dps.). I run with a smn on t13 now, he seems quite fine on dps even before the buff. SMN is fine. Not needing selene for good dps is a blessing and a curse at the same time, especially if sch gets nudged out in favor of the new healer.
