did 1.0 have an "uber" solo class?

for a time, it was Thaumaturge.

Thaumaturge at the very beginning could tank, heal [their heals had an additional Regen on top of that], debuff, nuke, and reflect damage and stun the mob while at it.

This was all changed [for the better] in Patch 1.20 when they became the nuking class.
