get some HP and resistances. no need for a 6-link flameblast, I did fine on my flameblaster in bloodlines until lvl 63 when I ripped. Reflect shouldn't be a problem for you either as most of you dps should come from the burn and another thing you don't always need a stage 10 FB to kill stuff
Oh I know, I hit 31, could finally equip Spell Echo and Faster Casting and thought "Wonder what this is like with a 6l Tabula" and equipped it. It was getting painful towards the end of Act 3 Cruel where I'd be running forwards, and almost explode when a group of Tentacle Miscreations would open up on me. Act 3 Merc its getting to the point where I need to pay some attention to it. Its a low priority at the moment. I'll sort the character out at some point. I only jumped on it the other day because I was waiting for traders to come online for a reasonably priced Chin Sol.
My attention is all on my BA Marauder atm. Took down Piety last night, couple of worrying close calls along the way. Really need to pay attention to what Nemesis Modifiers elites have. Killed a Whipping Miscreation boss over the corpses of about 6 others... it revived everything when it died and of course they all attacked me at the same time. If I hadn't been maintaining 6 Endurance Charges they would have instagibbed me... survived with about 15% health left, pressed basically every flask I had and ran away!
