I play the first one “sauliai” if i’m not wrong 
because it seems that that’s the mission most of people queue for.
[Topic to know if i should queue to other missions]
I think every other queue needs a premade party or a call because noone bothers to queue up for them.
The only one I see other than the first one is Gele and people kept screaming for others to join them.
Gele. Hands down. Pretty are pretty split between the two though. I like Gele because it’s impossible to fail. Not having a healer doesn’t even slow you down a little. It’s easy to finish all the bosses without even getting hit.
