Good solo quest for a wizard in Gianthold?

[Baloran]

Hi, my first warforged wizard just hit level 13 (he is my highest level toon on all servers) and I think it is time to leave the Sands and head to Gianthold. Since I've never been to gianthold, I was wondering which quests are easy to explore solo with an arcane caster (fire/cold specced) and which quests should better be done with a group.

I mostly looking for good xp/time quests, but loot/time is also nice.

For example in the Sands, I liked "Purge the Fallen Shrine" a lot, because it is easy to reach, has a shrine at the entrance (to refill SP), is fast and easy to run because almost all enemys take double damage from cold (Fireshield cold&Sup Freeze Clicky&Emp. Cone of Cold = easy win) and has three nice chests (got a portable hole there).

Anything comparable in gianthold?

Cheers,

Baloran
