When Death Knights were announced, I knew that was my new class, and I also knew that my Druid was probably doomed to be level 70 for good. I'd focus on my Death Knight, then my Hunter, then probably my Shaman for heals, followed by my Warlock. My Druid would just languish in Shattrath unless I was really, incredibly bored.
Yet here I am. My Death Knight is still my only 80, and now I've chosen to level my Druid ahead of all my other characters. I've purchased some heirlooms for him and dived right in, and I'm having a lot of fun in spite of it all. I think part of it is that it's just been long enough that I'm excited about the class again. I'm enjoying the things I used to enjoy about it, and I'm excited to try out new stuff like Savage Defense and Wild Growth.
But the big reason is actually probably because he's just a fun character to RP. I've built him up over a lot of years, in casual in-character conversations with friends, by participating in community-wide scripted RP events, and by writing and thinking about his in character reaction to various in game quests and world events and other pieces of lore. From all that, he's turned into a sort of wise but slightly curmudgeonly sage who is often confused by the strange new world of mortals, who sometimes lets his sense of justice lead him to do rash and hotheaded things, and who enjoys a good brew and a pipe full of dreamfoil with his wife at the end of a long day. It may seem weird, but I really, really like this guy, and It just got to the point where I hated to neglect him and his story when it felt like he had so much left to do.
I'm wondering if I'm alone in this. Do any of you have a character who just refuses to be set aside for long? Why do you keep coming back to them? Is it gameplay? roleplay? A sense of obligation to your guild, perhaps? Or is it something else?
