There should be a system where when someone enters a major dungeon sigil, and he/she is all alone, we should have a matchmaking type of thing like in pvp, because there is nobody to help me when i am doing dungeons, because all my friends are not on, or they are too low of a level. So when i'm alone it'll pair me up with people who are also doing the dungeon. But if there is more than 1 person, going into the dungeon sigil with you you will be paired up with them.
