Enchanter question

[WhatWhatWhat]

I decided to try something I haven't played before for P1999, so I rolled an Enchanter. Just hit level 20, so now I've hit the specialization question: Alteration or Conjuration?

There are posts on other forums about this, but they're mostly referring to EQ in its current state.
So, for folks who played chanters in original/Kunark/Velious, which would you recommend for those eras?

Alteration covers things like haste, mana sieve, clarity, charm, memblur
Conjuration covers mez, mez, and oh yeah, mez

I'm someone who would like to do tough groups, and high-end encounters. Does the mana savings on mez in hairy situations outweigh the fact that a huge chunk of the remaining chanter spells are alteration-based?



Thanks for the feedback.
