The choice of your secondary comes down to a simple question: How much of a control beast do you want to be?
/Storm and /TA are over the top. Storm will be an end hog 'til you get IOs or slot a bunch of endreds on your key powers, but it will turn out to be - imo - the best crowd troller in the game (if the player is good enough that is). /TA is less common, but equally beasty.
I don't think you can go wrong with any secondary tbh, but my top 3 choices would be Storm, TA and Rad.
Have fun.

cool, i am not a big fan of storm, only for the single reason that gale is a pain in the [censored] for other heroes. When playing as a tank i found that everyone getting blown away is just a little annoying and harder to control the aggro.
but not sure if there is a way around that?
hadn't noticed there is a thread just a few lower with the exact same title and basic questions, so i have read through that and it answers a lot of things for me! think i will go earth/TA and be a massive team player

I was the noob controller tagging along with your lvl 50 ding last night and as Ice/Storm I found that my AoE Freeze counteracted some of Gale's issues. I was far from perfect in my execution though, and freeze misses as well as new adds are still gonna be blown away.
Sorry

Yea. Either you play the tank or let him pack the mobs, then use AoE immob. Immob negates knockback for a while. If you spam it you shouldn't have any issues with kb.
There are just too many tactics you can use with earth powers alone. Hope you get to enjoy it as much as I did.

My first earth troller had /Rad on it, bit of an end hog, took a long time to set up for each mob (quicksand+aoe immob+stalagmites+toggle+toggle, for example)
Earth/storm is lovely fun, but bring some spare cabs, or slot extensively.
Earth/kin is my newest addition, and after fulcrum shift, I think it's my favourite so far siphon speed is awesome, and the heal power is outstanding. Speed boost keeps everyone else on the team going, and with transference, you won't be having trouble with endurance after lvl 35.
Not to mention it's a toggle-free setup, so you could potentially drop stamina. personally I've gone without a travel power beside siphon speed, and I'm at lvl 45 currently.

Or take fly and use gale to knock mobs down. Which works great.
I too recommend 'Storm', Its not only conceptually complementing but one of the most spectacular powersets GFX-wise.
Its an AOE control monster (laughable on interior maps) and has only two powers that not overly wonderful in my opinion. Earth/Storm/Earth Mastery FTW i say, I love my one.
Hey
Got my tank to lvl 50 last night, and wanted to try and troller. Had a few in the past, but never really got on with any of them. I fancy using Earth as it seems like a good controlling power set, but wondered what to put with it
thinking trick arrow, any other ideas?
