Druid and necro both fit your play style well. Good arguments above for sticking the druid out, if not to 60.

If you decide to go necro:

1) Roll Iksar.

2) HP > Int (at levels 50+, to 200) > sta = mana

3) Since you are probably the least gear dependent class and don't have a large amount of plat to begin with, I would suggest considering some cheap WR bags (evil eye, light burlap sack) and some good 6/65 rings. The rings will make a big diff at lower level and last right on through. Necros often make plat by farming things like guards that drop weighty vendor trash. Might as well make that easier.

4) If you've never been past 8, take heart. 8-12 are the worst levels of a necro career. At 12 you get your first versions of staple spells, all through the 20's you get good upgrades, and at 34 they really start to shine. The 50's see a comparative dip in power next to enc/shm, but they remain solid.

5) Make good use of being evil.
