Well, foundation program was designed and balanced with maximum of level 200 in mind. Active players that were here from the start have surpassed it, and semi active players, or relatively new players have reached some level depending on how long they were hare and how active they were.
People are distributed appropriately along the curve right now, and I guess if foundation program is to be continued, some more levels could be added, so active players who were here for a while and have reached level 200 as reward, also have something more to strive for.
If foundation would continue during Alpha 1 as well, I guess it would be nice if level cap could was raised to, I don't know, perhaps 250-300.
