They're both fairly similar in concept. I have little experience with /regen, and even then it's mostly with the Stalker version, but it appears to have less mitigation and more actual healing.
Willpower apparently has more mitigation, though still less than most other defensive sets. However, the things which make Willpower really cool are the aura, which gives you huge amounts of regeneration when you're surrounded by many mobs, and the passive health boost power, which, when slotted right, can give as much as 30% bonus maximum health. And that's passive, mind you. Finally, Willpower gives large amounts of Psionic resistance and defense.
Note that both sets have Fast Healing and Quick Recovery. Both seem pretty just as easy to play as eachother. I just like WP more myself, partially because the concept of shrugging off pain because you're just that focused/[censored]/in touch with your inner chakra or whatever is really cool.
il counter that wp info with some regen info then.
regen is very good coupled with katana because of divine avalanche and you will not be depending on the mobs for your regen.
add in the new moment of glory (which is friggin sweet) that can and will do very well in pve.
lemme add my 2 inf with some more /regen info
As seph said, the regen coupled with a 1ry like kat will give you that extra defence from Divine Avalance, i also run regen with the stealth and combat jumping pool powers for extra mitigation, adding hasten/superspeed and putting a +stealth IO makes you invisible to about everything bar rikti drones
The thing, imo, that keeps regen above WP is Instant Healing and Dull Pain. While the mitigation is sweet on a WP, it has no actual healing power to get some hp back if you recieve some nasty AV agro or spike Damage. The "God Power" in WP is also un-buffable for recharge which is also worth bearing in mind, whereas the changes to MoG make it part my /regen's everyday life
Hey all. Been away from the game for ages and now picking things up again from square one (so much to learn).
Anyway, my question is whether Willpower or Regen would be better for Katana? I've heard that regen is easy and you can't really go wrong with it even if you make a few slotting mistakes. I have no clue about Willpower since it wasn't around when I last played.
My main consideration is solo or "self sufficient" gameplay. I don't mind teaming, but will probably be bumbling around on my own a lot while I try and relearn everything.
Might google this "Mids" thing that everyone talks about, but would like some community input.
Cheers.
