Last weekend was the second Beta Weekend Event for Guild Wars 2, so I spent most of the weekend playing it.
I already had a Charr thief I’d made for the last beta event, but I made a couple of other characters, a Norn engineer and a Human necromancer. I ended up mostly playing the engineer because I really enjoyed the class and the Norn starting area. The thing I’ve found so far is that each class allows for a fairly wide range of playstyles while each still keeps their own unique flavor. The engineer uses pistols, rifles and shields, and has a wide range of utility skills from turrets (some for healing and some for damage/control) to grenades to elixirs (providing buffs to the player and/or nearby players). I highly recommend playing quite a bit with different skill/weapon combinations because it really changes how the class plays.
