I don't play all that much over the summer, due to seasonal work.
The last few years, I've taken my PC with me, but still that's maybe 2-3 hours a week, tops.

The game is always better after a break.
I'll sometimes take 2-3 weeks off of the game.
And that makes it seem fresh again.

As does an expansion.
Or a new team combination to try.
Or a new spec.

Variety is the spice of life.
The last week or so, I've been done a few 15-20km bike rides.
