I can't seem to find anything existing in the forums which answers this question directly, so here goes.
I'm just about to hit 50 and so far, in terms of gear, I initially focussed on Int until I started finding spell damage gear, then I went for as much spell damage as I could.
I'm levelling Fire, cos I like the big crits (but my levelling spec, which most say should be frost, is not really the basis of this question).
The question is, should I be focussing on Int or Spell damage (or a combo of both - in which case how do I decide what the right balance is).
My fire damage atm is around 200 at level 48 ... my Mana pool is just short of 4000.
The main reason which prompted me looking for answers is that currently, alot of gear I can find for my level is a HUGE upgrade in the Int department, and almost nothing in the spell damage department, actually in some instances .. a large step backwards in spell (specifically fire) damage. However, if I want to stick with fire damage gear, I'm going to land up with some gear almost 15 levels old (some more) by the time I hit 50, which isn't too far away.
This led me to think that the reason there isn't that much spell damage gear which has int on it ... is because you're not meant to gear like that at that level.
For a bit of clarity .. all (well 90%) of my fire damage gear is the Cindercloth stuff ... I took up tailoring on the advice of Millions of people ;-)
Some of my guildies have even told me to dump the spell damage stuff, respec frost for levelling, and make sure I have the biggest mana pool possible, this will allow me maximum control and quicker levelling. I should then re-evaluate when approaching level 70 for the end-game, for which I would most certainly go (or respec back to) fire.
Thoughts, suggestions ... any and all are much appreciated.
