I move around alot, taking on varying levels of responsibility with various companies and moving in and out of my knowledge and ability comfort zone. I often move country to follow interesting work, so I speak with some experience of the sort of thing you're facing

In my experience, things nearly always settle down after the first two or three months. The first thing that "gives" for me is my regular end-game raids with my primary guild, because the fixed schedule just doesn't work when I'm pushing my own limits professionally.

In those times, boxing is actually my saviour when it comes to quality WoW time. Being able to knock out a few instances whenever I have time rather than having to fit in with a fixed schedule (or... God forbid... waiting for a PuG... *shudder*...) means I feel like I've actually done something in whatever little time I've managed to find.

Of course, whether that's good enough for you depends on where WoW sits in your priority list. For me it sits just a smidgen above "watching the telly" as a way to pass the time. I would suggest that's not a bad prioritisation!

If things don't settle down after two or three months, and the job is still taking up an unhealthy amount of time with no prospects of getting better then you have to weigh the potential benefits (as might exist in a startup opportunity, for example) against the impact it's having on your life and make a call as to whether it's still the right thing for you.

When all's said and done, and you're lying on your deathbed, it's unlikely that your dying words will be "damn, I wish I'd levelled that other boxing team", so grab every opportunity that comes your way and make the most of it.

Good luck!
