Ill/Dark vs Fire/Dark

[...]

I mostly play dominators, and often pets are skipped because they die so easily. 

 

On a /Dark troller, how do the fire imps hold up in level 50 +3/+4 content? What about hard mode Aeon or ITF? 

 

Better off going illusion for hard content, at least from pet perspective?

 Imps be squishy and run off everywhere......they either die or aggro more mobs. Ill/dark is a beast that can do so many things

Depends what you're looking to do. Fire has more area control than Illusion. Fire has Fire Cages, Smoke, Flashfire, Cinders and Bonfire. Illusion just has Flash and Spectral Terror. Imps are squishy even with heals and buffs, but so is Phantasm. Phantom Army can't be damaged, but you need a lot of recharge to make it perma. Imps hold up fine in normal +4 content. For hard mode content I wouldn't bother summoning them.

Thanks. That makes a lot of sense.
