As for pve, only very specific fights could you get away with a tribrid build, and why would you want it? What do you need purge for in pve (the whole point of a tribrid), unless your going for tome. As for tome, losing PoD if your havoc heavy does not make sense, while if your deep enough in conflag to buy the extended pacts for maximizing renegotiation you would not have enough points to even get far enough to feat the shock debuff.
No, tribrid is not very good for anything but a single target dps battle where the only reason for going all 3 trees would to be maximize your sustainable core dps spells with getting all 3 +magic damage feats, which I only use in sieges for pvp, not ever in pve.
