If you were to switch to one character....

[Zub]

i think i might only solo play Cata for a little while (couple months) and pretty much asked myself the same question.
To me the answer was quasi-immediate: i'll solo play my Paladin because:
- it can fill any role well
- it will probably level prot anyway, and fast groups is great
- it's the one i currently have done most achievements on/focused most on
- last but not least: When I come back to boxing cata (you know you will) i'll have a geared tank to boost my other toons. And god knows how everything gets easier when the tank is well geared.

I'm doing the same thing here as Zub. Pally has always been my favorite class and since they're still gonna be good for tanking in Cata, I'll work more on him. So far I haven't run ICC or any 10s yet, but he's the best geared toon I have. Atleast once I start back up boxing, my dps/healer won't pull aggro so easily. Hopefully Holy Pally will be better at group heals too so I can stick with my all pally team. Druid is second best imo for another candidate since they can fill out every role. Respecing would be a pain tho.
