Put ranks on dungeons for better rewards=]
I think this is a very good idea.
They had a vaguely similar system in guild wars 1 with the instanced missions where you have bonus objectives which generally increase the difficulty of the mission but you get an extra reward and XP for and are needed for completion titles.
Things like completing the mission in under 20 minutes, or taking down an extra boss, or making sure x villagers are saved.
A similar system in GW2 would make the dungeons way more interesting , on top of the variations they already have.
BOOM
Thanks! Never played Gw1 though, just thought of it when I played this acrade game where I got a rank and I was like why can’t guild wars 2 dungeons be like dat lol
