Multiclassed cleric for second life?

[Micki]

Hello everyone. I am a long way off from tr:ing my cleric, but I'd like to start planning for it - what gear to collect etc. And to do this, I need to know what I will be doing for the second life. First life: pure cleric, for the second life I'm considering multiclassing. Atm. my cleric is an offensive caster with some melee ability (healer too of course). For the second life I'd like to do 18 levels of cleric and 2 levels of something else (18 levels of cleric to not affect spells or sp). I would also like to be mostly offensive caster. I'd like to multiclass to get better survivability, and was maybe thinking monk? I love evasion, but would I want to give up using heavy armor for it? I love my offensive caster cleric, but her problems are that she is slow (low dex) and she can't take hits (low ac). And since since I mostly mass heal, and often get aggro, being slow and not good at getting hit - can be a bit of a problem.

Advice please?
