The beta is mainly for testing, so if you were using it to trial the game, it is guaranteed you will be disappointed at this point in time.
Right now, they are making sure that it runs on all computers so they got the bare minimum needed for those tests. After the game passes all hardware related tests, they will start introducing content to start balancing the game. But that could be a while off.
If you are unsure, just keep an eye on the forum once some updates are released, and players start commenting. But take into account, that it will be biased towards bugs(since thats what betas are for).
Or if still unsure, the demo is in March.
