Heroic is coming for real (insta 85's) and the window for the one-time freebie isn't that long. I'm a gold sub at the moment (not sure if they put restrictions on the freebie based on accounts?) but I am not going to waste the "gift" as it were... though I'm not sure I will play it either.
I know I will make mine on a regular server (not FV or zek).
I'm partly tempted to boost Banner (my 27 troll Sk that I was roleplaying a while back) but then again the fun of him was everything being silly hard in old content. So that might be losing the plot...
One thought is recreating my necro that I moved to FV (now level 77). I know how to play it reasonably well. Most of the other classes I have played a lot I have no interest in picking back up (enchanter) or I have high enough characters (beast, ranger) that it would be a waste of the freebie. My FV necro has gear I can never replace (even as an 85), but I just haven't "felt it" in respects to playing on FV in a couple of years.
My brother was trying to talk me into going rogue (which I have played to 30-55 half a dozen times, but never for any sustained depth of play) but I'm not convinced he'll actually come back and play for more than two logins, so that seems like a potential waste... since I don't see solo/molo rogue at 85 being the most fun/viable for me.
Monk (not frog) keeps crossing my mind too. I have played that a bit up to 65, but would have a lot to learn.
