My personal opinion is to Keep 2.0 as a New game, a new world, a new server, a fresh start, hopefully this time the game can take off with the fact you removed your limitations by running a tiled based engine previously as it suited that time peroid.
Just my thoughts
+1 no need to bring tons of level 70 accounts MANY of which were bought and sold accounts with real life money from players who quit or level accounts to sell for rl money (If i were ej iI'd keep track of this and delete bought accounts as no one should make money off ej's game.
and no need to bring tons of high end gear to just bring more imbalance to a FRESH server/game. Keep all that on x1.
