Hrmpf, first the game doesn't update properly (probably because I had started updating to a previous version but never finished it) so I've had to completely redownload the 2 Gb client and now I've go no mouse cursor in the menus and only a black background which apparently can be fixed by validating/repairing the files, which is taking far longer than downloading the 2Gig did...

EDIT:
So I finally got to play and at first I looked at the Unlocks and thought that HiRez had gone back to the insane prices, but then I finished a round and got 1600 Exp for a rather sub-par performance, (not sure if it was doubled for the first win) so they seem to have increased Exp gain quite a bit.
Will have to play a bit more and see how this pans out, but so far I'm pleasantly surprised at how much they've changed.
The customization isn't all that extensive yet, but this is far better than locked classes with no customization at all.
