Fire Rose is a pretty solid DoT, but I would also use Electric Bolt and Vampire Arrows, since that way you can have three DoTs going.
As for the rest of the elites,Thunderclap is pretty useless since, as a mage, you already get lightning and discharge. I've never used it, but it could be ok when running away from a mob when your lightning and discharge are on cooldown.
Fire Arrow is probably the best one that M/S gets. With that buff on and my shot at level 50, I can hit for almost as much as fireball.
Fire Rose Explosion is a decent skill, although it's kind of a waste of the Fire Rose DoTs unless you time it right (i.e. just as the Fire Roses are about to wear off).
Flame Spirit is junk. It's cool looking, but the ability that it casts, Flame of Fire, is broken. The only redeeming quality is that you need it to get the Magic Crossflow buff, which is an amazing skill.
Power of the Wind is useless unless you're going Wind Mage, since it cancels out the Fire Arrow buff. I'm a full fire mage, so I haven't really tested this ability out (working on a wind mage, atm) but the critical hit rate (Fire Arrow) looks to be better than magical accuracy.
Since Fire Rose Storm is a passive, I haven't really noticed it, but it's a pretty good skill that increases the damage of your Fire Rose DoT.
So in short, Fire Arrow, Fire Arrow, Magic Crossflow, and Fire Rose Storm are good elites. Hope this helps!
