How long does it take to get from 200-210 on a not-that-well funded character?

1% increase in DPS is a lot to begin with, but comparing the Lumi with the Cannonner, it depends on whether you need that extra %HP/MP. 10stat is probably not going to be 1% of your pottable stat. Leave Lumi for 3rd. You can nuke golems with Reflection brainlessly, so it's more of a grind than a pot-burner.
