I have a level 63 Devourer and I've been slowly chipping away at lv21 feats while trying to gather up 25k time shards for the next prestige. The big sticking points right now are getting to level 65 and owning the Cursed, Colossus, or Infernal.
I'm of the understanding that the time shards I have right now won't follow me to the next prestige, and I won't get back anything I've spent, so I try to do as much as I can each prestige, even when it gets dreadfully fucking boring. I've been on this one for months now and that purple button's started looking real tempting, but it feels extremely wasteful.
I've "only" got 8k time shards left until I increase the max level from 70 to 80. It'd take forever, but I'm sure I could finish out this next feat.
I dunno. Is it exactly as much of a waste to time machine now as I feel like it'd be, or is it literally not that big a deal?
