Guild Wars 2 is now F2P as of Saturday afternoon

[FatherXmas]

The F2P restrictions are rather light.  No restrictions to content or game types (PvE/PvP/WvW) other than level.  No restrictions to professions (class).  No level cap.  Chat and e-mail trade restrictions to combat RMT from using it.  F2P can only buy proxy currency with real money vs in-game currency but they can convert the proxy currency into in-game currency.

It's a very casual game in PvE.  Combat is action oriented, you can't face tank well.
