That depends on what you want to do with it, as always.
If you're soloing on x2 then recharge and hp (hp over regeneration) is... ok. Not great. Some factions will still murder you.
If you're soloing on x8/tanking for a team without buffs then you're going to have to get those defense numbers up or die horribly to every alpha strike that Moment of Glory isn't up for.
Weight training: Because you'll never hear someone lament "If only I were weaker, I could have saved them."
So I'm playing a Steet Justice/Regen brute, but I'm having a hard time figuring out exactly what I need to do with regen in the end game.
The build I made has 614% regen w/o Instant Healing running, 1768 HP w/o DP running and 63.75% recharge w/o the spiritual Alpha slot or Hasten on. My real question is do I need to be softcapped? My build hasn't got any defense really, outside of weave. Stacking recharge and regen won't cut it for me?
