Well at this point I dont think we need more than one healer class really. Down the road yes but not right now.

On that note, a fantastic main heal in ffxi was....puppetmaster.

Yes I said puppetmaster lol.

After you hit the lvl 40-ish pts using your whm puppet you could endlessly heal with unlimited mp using the right maneuvers. I did it many times and ppl were always amazed pup could do it lol. No downtime and the automaton could easily keep everyone in the pt at full health. Tons of fun that pup if you played it right.
