Radical thought...remove the off-tank?

[Rita1989]

many people build for off tank and only off tank and thats their fun.

You shouldn't ever do that though.

Ideally in any difficult fight you should be sharing the main tank role to help maximize raid dps and get the most out of your defensive cooldowns.

Considering this would be for roulettes and easier content, why not? It worked for raids. Just leave it for hard content. This wouldn't solve the main problem though, leveling roulette.

That wouldn't even work there are too many fights in the roulette that are dependent on 2 tanks
