Fire/Fire or Fire/Regen for Zone?

Sure, /regen gives you some pretty impressive recovery but if you combine Fire and /Fire, FE gives you some absurd damage potential and you have slow protection, a damage aura for stalker reveal and good resistances...

so? Fire Melee /regen? or /fire?

Regen for sure.

The ONLY reason to do anything except regen is if you already have regen toons are are bored of it. It is twice as good as anything else at this point.

Regens tougher for sure, But for Zone that isn't as useful as it would be in other places.. unless things are different on the servers I play on, Scrappers are rarely the first targets of the villains... Most of the time if the Villain Team do take out the Hero team, the Scrappers are the last to get taken down... Because they are tough yeah, but also because they are the last to be focused on... In zones if it comes down to that, Regens are tough but once the team is wiped out and the villains focus on your scrapper, regen or not you will most likely die... maybe have the chance to run back to base if thats your choice... Fire has perfectly good survivability in Zone so you will only get taken down fast if multiple villains are hitting you, it would take a decent player to kill you still solo, a lot longer than whats usually granted for someone to run around and kill you before one team wipes the other...

That being said its always handy to have a toon that can adapt to situations, if your zone isnt that populated and its say 3v3, then even if your team mates get wiped... depending on who your versing/where your fighting, you may be able to fend them off and keep the fight going until an alley comes back from the hospital... For that reason Regen is teh winner.

I've played Regen and Fire in Zones... Regen you feel a lot safer on, Fire is fun though and the damage is nice on a fire/fire... So long as the stalkers aren't SRs then blazing aura should flush them out... thats if your hunting them not waiting for them to AS you... Altho I would feel confident ASing a scrapper with Blazing aura if I had high defence... if the stalker is competent at it anyway.

I ramble lots.
