Best Minion/Lt Killer
Both are good minion/Lt slayers... but then even one of my cruddier altsfor killin', a wussy FF/dark defender is a good minion/lt slayer.... It's bosses and up you have to worry about. I'd go Fire/Storm troller with Fire Epic later then you can merrily slaughter (sorry arrest) the bosses and elite bosses easily too... Probably be able to do that before even hitting the epics. Then again do controllers get bile spray from Mako? That would be tempting... perhaps overkill.
Probably suck endurance like shinolah thru a goose though like my Illu/storm does if I bother to use all the powers. Had to grab the 2 crafted enhancers that can be stuck in health to always grant faster recovery. Still often tempted by the Energy/Popwer epic for conserve. Always fall back to having that mez protection from PSI though. hehe
Late level fire control/anything you want destroys soft targets. FYI. Even have a pal that leveled a Fire/FF (so no damage assist whatsoever from the secondary at all) still rakes minions and you have enough control for LT's to keep them in place. Not the kind of Farmer Burn build that kin or rad are... but nothing to wink at.
Good luck whatever you choose.
TY for the input. I do like the control that comes with being a controller and I've been impressed with the sheer damage nastiness of /Storm + -KB effects (have a higher level Plant/Storm). I saw the additional damage potential of throwing in Hot Feet and Bonfire; so I had to roll one up.

I'd recommend rerolling the ice/fire (they're level EIGHT, for pity's sake) as a fire/ice or fire/mental. Fireball plus firebreath drops even con minions with neither build up nor aim; blaze finishes off one lieutenant, and the fight now looks very different...

So you think you're a hero, huh.
@Boltcutter in game.
I already have a Fire/Storm Controller that seems to be putting out some decent damage at lvl 27 and am currently putting a Ice/Fire Blaster through its paces (lvl 8)
Which of these two do you think would be best for high count minion/lt mob killing/survivability at comparable levels?
