Well, Totyen, I certainly can't add much wisdom to what has been said, other then to point out, that one of the nice things about EU is that there is not a continuing monthly charge. You already own everything, and your avatar is well developed. Keeping him alive costs nothing, other then logging in periodically. As spring hits the air, I will play a lot less, but once the hot summer arrives and I stay inside more, or winter, or rainy days.. the ability to spend a few hours not thinking about other issues in life, is quite nice. Being scammed is almost part of this game, just don't hand your armor to your friend to have it dyed.
For every "bad" person, I think I have met 10 good people. That is almost a better ratio then in rl.
Good luck whatever your decision.
