That's assuming you have one. Not all groups plan everything out and balance class, skill distribution and battle orders beyond basic target calling. As for not getting much out of the Glyph, well, that will depend on how well he's able to keep multiple enemies around, or at least right next to, him.

To the OP, definitely bring Glyph of Lesser Energy if you're going to use Conjure Flame and Mark of Rodgort.

[Cyclone Axe][Eviscerate][Conjure Flame][Mark of Rodgort][Glyph of Lesser Energy]["For Great Justice!"] ...and two other skills, preferably signets or very cheap adrenal skills (perhaps [[Keen Chop] - cheap, spammable and does adequate damage) 'cos you don't want to strain your Energy much.

Now, that said, it probably won't be all that effective, especially later in the game, and definitely not in Hard Mode - the burning will stop on most of the critters and they'll start healing quite quickly if you leave them alone for any length of time. And, since they'll scatter to chase after your squishies, that's virtually inevitable. Even worse is when they have a Monk type, as many mobs will. Make sure you go after those first, at all cost, along with any you suspect can resurrect.

Still, no real harm in trying, at least if the people you play with aren't the type to whine that you're using a (very) non-standard build and ragequit. Heck, maybe even have them try help to try and keep the mob in a bunch so that you can get at them easier.

Good luck with it.
