By Boundless Health do you mean Colossal Health?
This is what I did:
- Bio Shielding... all the way. Can't do without the absorb, and the heal is spesh.
- No weapons perks because I like to freedom to change often
- Got the Troll Form perk special. I think this is Form of Troll 3. It adds 6K AC for a little while (but snares you at the same time).
- Genius 2
- Pumped points into Colossal Health. Since I solo a lot this line makes sense for me. Adds both good HPs and some really nice bonus heals.
- Now that I have spare points I am raising Form of Troll for more HPs.
[edit]To summarise:
I believe Colossal is more suited to soloing because of the couple of extra heal specials (Life Tap, oh yeah!). Form of Troll is more suited to team-based play. The both are very good, and I think most enforcers will probably look at raising both if they can
