I went in with a drengrs lash/diamond lance build with spirits of abayent/kephris build, the only source of healing I had were from sol invictus from spirit of kephris and rarely from my support ar with slice and tear, last I checked all of those were still working as intended. As for boons I invested in class ability and grenade regen, solar and stasis slide ability. I GREATLY disliked it at first, but now I'm having fun and enjoying it.
