Ah, right, so they're powerful when fielded in mass quantities. That just brings the running count up to All Classes + Immortals now.

In party's he is the security guard. making sure nobody GETS to the casters while they rain evocation (and others) on the field. and they can clear paths with the forced march (works best on narrow corridors or bridges.)
Yes, lets just hope the entire campaign is based around monsters who are too stupid to sidestep the guy in full armor who regenerates like mad, who are all inexplicably placed in chokepoints favourable to the party, and have no alternative means of movement.

besides, think epic levels. even greater deathpoint and fast healing, this might turn to bee too much in the super-high levels. (say, level 25 Immortal. fast healing 25. deathpoint -70. silly powerful. and with that high hit die, even your wizard will find it troublesome to defeat him. ever.)
You're absolutely right. The wizard who has access to epic spells capable of ending whatever planet they happen to be on will assuredly quake in fear of that fast healing.

In some way, he is anti-caster. because they might run out of spells before he runs out of hitpoints.
Actually, that just makes him the anti-purposefully-handicapped-caster. All a caster has to do is chuck a single will-based save-or-lose your way, and that's the end.

The idea is cool, but within the context of a D&D adventure, being really hard to kill via hit point damage and nothing else isn't very useful. At best, you'll be the last party member standing, and so when the monsters have looted your friends' corpses and walked away ignoring you because you're still only doing pinpricks of damage, and they're too frustrated to bother finishing you off, then you can write everyone's epitaph.

At worst, they had a caster or scroll of <insert will-save spell here> and you're dead too.
