Tanker AOE Secondaries

The last time I played a Tank, I think there were about 6 secondary powersets; now Mids lists something like 13. So of all the secondaries, which is ‘best’ for an AOE focus (in terms of damage output)? Is it still /Fire or /SS [ugh, Rage crash] or has something like /Elec surpassed them? Will it be Titan Weapons? TIA for any inputs... I’d like to roll another Tank and I like to focus on AOE.

from what I understand titan weapons is primaraly a aoe focused set, after that I still think its fire.

Here are some set that have good aoe damage and are not super strength:
Titan Weapons has great aoe. It has a PBAoE and 3 huge cones.
Firey melee: has 2.5 aoe attacks in Combustion, Fire Sword Circle, and the breath.
Ice Melee: There has some changes to the set a while back, Frozen Aura now does foot stomp level cold damage as well as the sleep, and Frost is a great damage over time aoe. Ice patch is always fun.
War Mace: It also got buffed and now is a great burst aoe set as well as having good single target
Kinetic Melee: This is a newer set, it plays like a blend of claws and energy melee. It has a good pbaoe in Burst and a 30ft ranged cone that does knockback in Repulsing Torrent. If you can work with the knockback there is a lot of aoe potential there.

Also since Tanks now have access to Villain epics, Mu Mastery can give any set AoE potential thanks to Ball Lightning and Electric Fences.

Surprised nobody's mentioned electric melee yet. It's got a couple of single-target attacks but also some quite decent AoE powers including a melee cone, a chain-effect lightning attack, a Total Focus style single-target attack with secondary AoE damage...and, of course, Lightning Rod.

I should note, if you make a Shield/Electric Tank, or an Electric/Shield Scrapper or Brute, and take Superjump, you can chain Lightning Rod, Shield Charge, and Leap Attack and the poor 8-man mission spawns will never know what hit them.

Just noting that, Shield/ is a great primary to pair with an aoe set. You get Shield Bash as another nice aoe attack, but you also get Against All Odds, which increases your damage by about 5% for every foe in melee range, up to 10.

Meant Shield Charge instead of Shield Bash, whoops.

Does Shield/ look best when paired with a weapon secondary? I'd think it would look strange to have a shield in one hand and nothing in the other, but maybe it looks ok?

It's all personal opinion really. I have a Shield/Mace and think it looks awesome. A friend has a Shield/SS and it looks fine. There are, however, some secondaries that cannot be paired with Shield/. Offhand, I am not sure what they are.
