I'm not sure about GW2 yet. It's a bit different than other MMORPGs I've played, and not all of it is in a good way. The combat seems... clunky at times, like there's a slight (but noticeable) delay between pressing a button and your character using a skill.
That aside, when this huge worm boss spawned yesterday in Caledon forest and a bunch of players worked together to beat it, that was classic MMORPG fun
That was fun to be running from one side of the town to the other to turn a quest in and see 50 or so player trying to kill a boss, and I just hop in and its just so much fun.
IMO this is a game you play with other people fer sherr
