Friends dragged me into this game we all got to level 80 but they are hardly on... What are some fun things to do at 80... Don't say pvp because I've tried it and without friends its frustrating.

jumping puzzles
dungeons
world events ( dragons etc )

if you have to ask maybe...just maybe

might be time to join a guild. good ones have events/dungeons/world boss hunting/ guild missions going all the time

tbh i never really liked WvWvW until i found a good guild.
i've never been a huge fan of the PvP, GW1 PvP was so much better.
grind stuff for materials if that's your style.
make a new character.
world completion.
do achievements.
finish your character story.

You play an mmorpg, but you don't have any friends...

make new online friends ?
