1: turn your screen brightness down, you'll blind yourself!

2: the battle system in 1.XX was updated through the patches to make it more user friendly than it was at release.

Being alpha, they don't really need to care too much what the battles look like, there are people working on those while the tests are going on. The point of these alpha tests is to see if the servers can take large numbers of players all fighting in the same area on different worlds without the servers killing themselves & ensuring we never go through the dc festival that was the last event...

All these negative posts about something that is so far away from the final product is pointless, if you must criticize, have a half valid point at least & then remember its a server test.
Game test comes with beta.
