Sounds unhealthy. Have the forum trolls made you feel guilty lately?
I never get too nostalgic when playing, I still talk to all the same people years down the line, and we reminisce about the old days, but never get annoyed of feelings of nostalgia.
I just give into my nostalgia - I don't keep an active sub to WoW, but I browse these forums for updates and whenever I get a 7 day pass, I use it (9 accounts) and every two years - at the end of the expansion - I pick up the game for like 10 bucks usually on special somewhere, then I sub for a month, level to max and do all the quests, raids in LFR, scenarios, etc. I think the game is worth 25~30 bucks every two years, just not 410 bucks every two years.
Warcraft has too many good memories for me, too interesting a world to not level my druid and indulge myself
at least this way, I don't get burnout and the game remains something fun.
