DArtagnan, just so you know, Archangel doesn't have access to the beta and he never played it. He base everything he says on what he reads on the Codex and on the official beta forum.
Going by your other comment of playing a beta build before the time extension, that was a long time ago. It went a long way since in just the last 2 builds. Avatars don't blend anymore. There are a lot more generic and class talents to pick from since a few builds back. Combat was polished a lot: idle and recovery have different animation (used to be a pain to differentiate these), you can queue actions, party members are more responsive, balance is much better (still need some polish and bug fixing though).
There are a couple of design limitation caused by lack of time though (like group stealth), some might get patched after release or improved in the expansion.
