Still undecided. I have a few conflicting interests.
Factors:
- what will be the sys req. to box 5x cata at reasonable settings? i do not intend to buy yet another bunch of new parts
- how well will cata run on linux, and what changes will be needed, if any?
- this will be my first expansion, so totally not sure what waiting times, server issues, bugs are going to be like, or how annoying the phasing is going to be
- how easy/hard are the instances going to be? will it be worth to box pve for me?

Personal:
- i have more and more interest to go all out on hardcore raiding with my shaman, not much time left to box properly, so scaling down is an option
- i really like the comfort boxing gives me, afking in a dungeon and not having to deal with idiots
- i'm really looking forward to boxing the rated bg's, with my 2 teams, 5x shaman + 1 disc priest / 4 dk
- my favorite toons are spread among different accounts, transferring toons over is not an option for me
- my professions are spread among the accounts, that is a huge benefit as a boxer, not sure if i want to lose the money making factor

I do intend to keep 5 boxing, though it will be more a side project like it has been in the past few months. And probably with the focus on pvp.
