I agree that wipes are necessary if the situation warrants it, but if at the end of alpha there have been no changes to the core game structure, or if there were no exploits that would give a player an unfair advantage, then a wipe would be unnecessary. As it is now, if we moved into closed beta, there would be no need for a wipe as there haven't been enough fundamental changes to the game design to require one. As you say, it would not be
fair for the people like me, that have spent a lot of time developing a character
fairly and without exploitation.
Although I'll be realistic, chances are we will find something that will force a player wipe. Just saying that if it isn't needed, don't do it just for the heck of it, even if it means transitioning to another stage of development.
