Willpower AFK farming is surprisingly safe

Softcapping defense and resistance to the enemy's damage type isn't enough at high enemy saturation like what you get on the asteroid map, so I figured regen needed to be the 3rd element. Threw this WP brute together to try it out and it does quite well at +5 with very high saturation, with the downside being no offensive benefits from the secondary. Is there a better option for safe +5 farming that has better offensive output? This is pretty slow, but only has alpha slotted so far.

I stopped the video after I leveled because I wanted to show this with no inspirations or temporary powers/buffs, but you get the gist.
