Basic, Boring Question: What to Play?

[E-Queue]

All you alt-aholics out there, I need help deciding which of my many noobs to focus my twinking funds and free time on. I have a bunch of contenders that are all pretty fun in their own way, but I need to quit jumping back and forth between them.

I'm looking for the following characteristics:

1. Idiot-friendly - I'm honestly pretty unskilled at EQ. The fewer clicks per minute required, the better for this fool.
2. Not too gear dependent - I'd like to farm my own upgrades as I go, but ideally I'll be able to get by mostly in rags (which a few exceptions - see below).
3. Great soloer - I'm an old man now with intermittent pauses in the action. Hopefully I can accomplish most of my fun on my own.
4. Able to find groups - For the times I have a solid opening, I'd prefer to group and not have too much difficulty landing a spot.

This is on the Blue server. I have the following available for twinking: a fungi tunic and roughly 20k in cash.

My current toons are:

1. Iksar necromancer (27) - Checks most of the boxes, but I'm not confident I'd get many groups. Possibly difficult to play at high levels in dungeons, etc.
2. Barbarian shaman (24) - Seems like a very powerful class, particularly with a fungi. I'm just afraid I'll get to the 50s and regret not having all the expensive toys shamans need to be their best (epic, JBB, big boy spells).
3. Human monk (21) - Very solid so far, though I expect my ability to solo will drop pretty dramatically at higher levels. Haven't minded being a human yet, but might regret that around Level 50 when regen really steps up.
4. Erudite enchanter (16) - Checks most of the boxes as well, but definitely higher on the difficulty scale. Doesn't benefit from the fungi, so might not be as smooth a ride for a while.

Anyway, sorry for the stupid question. I know this is asked about all the time. But if any of you have played most of these classes and have any advice, I'd appreciate it greatly!
