I started WoW just before I began working fulltime again. I played SWTOR for 18 months before that whilst taking a sabbatical from work. I never missed stuff in that game. Was online a lot. Now I log in daily but in 6 months I've played the game, I've taken two one month breaks and generally just stuck to one character. A (former) friend of mine in that time got himself 3 550+ers but with time restrictions I just cannot commit to that.
Initially it irked me, but now I just enjoy other aspects of the game. I keep gearing my main however I can but I augment my love for the world by not playing more but reading the books when relaxing and listening to the music at work. Much less pressured and I don't need to deprive myself of sleep in order to keep running the gear race.
I'm in a guild that has schedules to suit me but not the interest in meeting those schedules so it rarely works out. I don't mind. I just crack on. It feels good besides the times when free time is made for raiding that then gets used up spontaneously by something else to fill the void.
