Yes, it should be available in Europe. I was able to get ahold of it at import pricing at one of the special retailers in town. If Norway can import it by now, I'm sure the UK's got us beat by months.
Yes, indeed. You could make a tanker archetype, one of which I believe wield a hammer of sorts. You could even configure your hero to look like a knight in shining armour as well, if you feel so inclined.
And of course I'd be interested in knocking about with ya- the game features some pretty intuitive features, one which enables you to 'sidekick' another person five levels or more below you to, ah, shall we say even the gap, pushing your character to my level minus a few temporarily for the sake of grouping together. Works great, really.
