It's depends.
I do dailies because of 50 gems per day. I hope that I will roll something good in the future (40 rolls = 3 SR himes, 3 SR "monster" eidolons and 2 SR Light Bows, no SSR ever)
But quality of the dailies deepends on needs. My team now fire/dark, and I "maxed" the dark one, so I will run 25pts fire dailies and 8pts others.
