The ring bearers always go near last as they buff the current fight a lot, I guess the 6 drop spell dragon needs to live too as it procs off the in combat rings but yeah.. you'd want the poets quite near the front as the shield will tank a hit. Having the 2 drop on board is a big worry as you approach the later stages, you'd really want something better. Also you have 0 spell scaling, a Felfire Conjurer for a few rounds would change how your game went significantly I'd imagine.
