Tome of Eric looked better as it is. Seems it adds to base dmg only and is not taking + dmg modifiers into account.
Doing
this a.t.m.. For long boss fights Demonic Supplication (Long time demon illusion) + Fire Lance looks better to me than Inferno or Chains of Anguish.
Doing Villa melee mobs with this setup works usually like this: Pull with Flame Lash, start HellStrikes Combo, cast HellfireBreath, finish Combo: dead. If there is a 2nd mob, most times another HellfireBreath and a melee hit does it. If not, then I Eat your Heart + maybe another Hellfire Breath finishes them.
On solo bosses or larger groups of mobs i start with my long timers: Molten Steel, Toungue, Demon, Pillar and FireLance (incl. HellfireBreath whenever it's up).
Will be interesting to see if on long time fights the improved fire based casts can make up the missing Searing Curse / Flame Cleave on melee attacks.
Gearwise i am at +659 Fire dmg without any gems in the Nemedian Cursecaller armor yet (can't decide

). Destiny i went for +attack.
Still i don't have experience on long time raid encounters, especially running oom/oos, recast timers, need of Purge / Fear Resistance / Protection, but hopefully that will come soon.
