JUST HIT LVL 30 NORN MESMER!!!
I have a level 80 norn mesmer (his name is Subtle Norn Mesmer xD). I generally use Time Warp in a lot more instances then I do Moa Morph and very rarely use the AoE stealth skill (your utility stealth is strangely better). Time warp allows you and other members to go crazy with DPS. Moa Morph does have its uses like making a dungeon fight versus trash mobs a lot more managable, but it’s generally used a lot more heavily in PvP.
The racial elites are mainly for your personal amusement. Don’t get me wrong though. They are practical to use but generally racials aren’t on par with class skills. Hope this helps.
For a mesmer I would suggest Bear form, since you charge the enemy from afar and knock him down. Then you can change back and do your mesmer tricks on him.
The thing about the racial elites is that while they’re nice and flashy, most of them are significantly weaker than the normal elites you could use. Become the Wolf is situationally useful, but the others are kind of eh.
First elite I think you should get, IMO, is Time Warp. It’s probably the best PvE elite that Mesmers have right now. If you’re leveling up mostly through WvW, then I’d probably get Moa Morph instead. Either way, pick a profession elite before a racial one.
