In all honesty, if you invested the time to get to 80 Im amazed you havent invested any time in any research. No, no raids. Outside of pvp the end game is dungeons and fractals as well as farming the bigger world events, use
http://us.gw2stuff.com/events/eu or get the overlay from the thread in this forum to chase the events. WvW seems to be the big draw for some, as for cool goals, others just want to get 100% map completion, some want to get all the gear sets from dungeons, some want to craft a legendary. Others just quit the game because derp no end game.
Chuck in guild events, and lol living story stuff too.
