I can understand the difficulties of having one player appear more powerful than others and a DM trying to counter with more difficult opponents to present a challenge. His DM might not be complaining that he can't TPK the party (Boo hoo you lived Grr!) but rather that the only way he can actually challenge the forsaker is by making encounters that end up seriously lethal to everyone else concerned. The dilemma he's facing is whether it's better to let the Forsaker have an easy, if not unglamourous ride, or if it's better to pump up combat to deal with the Forsaker's ability to not die easily.
Unfortunately I can't say the campaigns I've been in have had any success in dealing with this kind of problem. Numerous party deaths (i think i died 6 or 7 times in 9 levels for example) led to gripes about how overly difficult the game was, when the game was just responding to the power of some players who were getting out of hand in terms of their power. (Whether or not this is right itself is a whole other matter.)
On the bright side however, I can't see this being the exact case for you... as you said yourself, you're defensive but not overly offensive. It's not like some cases I've heard of where a PC is better than everyone else at everything. The Rogue out Fightering the Fighter, out Barding the Bard, and out Spellcrafting the Wizard while also being neigh invulnerable and an over-Rogue in his own right, for example. The biggest danger is if other players dislike your power, and as you haven't brought up their reaction, I don't think it's part of the equation (yet).
