Haste and Refresh are really not that worthwhile with Accession. Convenient? Situationally. I'd only really bother Accessioning buffs that are otherwise self-target only (eg, Temper). For everything else, it's not really a big deal. It's, like, 2-3 spells every 6 minutes.

I mean, you're not the only mage in the party, right? Split Haste duties with the WHM like everyone else.
