5 Dooms + 1 Agony = Minimum 5 minute, 24 second fight. This is 384 seconds. Thus you should have 34-38 Conflags. You only have 26.
You should have had 29 - 32 Chaos bolts, you only have 19.
Your immolate needs work too - 28 casts means 150 ticks, but you only have 106. Either that means you were casting Immolate on adds or you were clipping a lot.
Don't Immolate the adds, just rain of fire. If Conflag comes off cooldown, switch back to XT and use it, then switch back - you're fishing for Pyroclasm buffs, which increases your dps by 6% x (Crit % + 30). Not using Conflag means less uptime meaning less damage from other spells.
Everything looks good numbers wise, for your gear.
