Actually, the only reward that we will receive, for now, is a bonus energy when the game goes to full release, but, this bonus isn't a permanent bonus, and isn't intended to every palyer, just the ones that bought Crystal energy.
What i'm suggesting is a permanent, visual reward to every beta tester. For example: every closed beta tester that comes and register at the open beta, when it release, will get a full set of 3 armors, to choose how he would like to look. these armors would be horrible, in terms of status, but quite good looking, maybe with the inscritpion "BETA" at the armor, or the greek symbol for beta in both armor and helm. the 3 armors would remember the 3 begginging armor, but with looks that no one else could get, making as a form of thanks for all the colaboration that we gave to you during this test (massagin own ego).

I can't stress enough that it need to be a untreadable reward, that can't be sold to npcs, either, and that would not give any status, functioning as a visual equip only! And i can't stress enough that the reward need to be permanet, and non monetary related, just for us to show the newcomers who helped to develop the game, as the testers we are.
