Can't join friends on campaign areas

[karma]

There is a way for ppl more than 3 levels apart and still be able to join.
Solutions, u need a 'middle man/woman', it's true that only players within 3 levels can play together.
So normally a level 27 can not join a level 21, but get a level 24 player, and have this lvl 24 player invite the lvl 27 player and this lvl 24 player invites the lvl 21 player.
and u end up with 3 players lvl 21, lvl 24 and lvl27 in same mission.

Final note, this issue of players not being able to play together has been adressed before.
Ever since the lvl cap raise from 26 to 31 it was suddenly not possible anymore, Carapache promised us that it wld b adressed.

We r still waiting for a fix, so dev team a friendly reminder to solve this.

I tried this out with two friends and the man in the middle didn't work for us in pve. I was a level 15. I invited a lvl 16 and a lvl 12 to first mission. The lvl 12 couldn't join. Don't know if there is a certain order you need to do it in so it will work?
