New player with a few questions.

Thanks to all of you that replied. I'll be choosing Summoner after taking a look at my chooses, I quite like the DOT stacking playstyle. Speaking on Aeroflow, seems I was approaching it backwards (typical videogame dilemma, if X is good: never use X in fear of wasting it). What of virus? I am aware it is a debuff, but should I bother using it or is it not worth using my MP? Additionally, should I use pets or are they more of a liability in dungeons?

I'm glad to hear I'll get access to appearance customization, I do like having that feature. I'll definitely get to level thaumaturge/archer to get Cross-class skills that I'll need.

You should always be using a pet. They are a major portion of your damage. You should also always have them on Obey though. If you are in a party with a tank you will want to use either Summon I (emerald/garuda) or Summon III (ifrit).
