The thing is that I understand why they did it, people hate defense mission if I had an option to not doing I would stay on railjack, imagine whole team deciding to stay on railjack because everyone hate it which would make finishing impossible, that would most likely lead to host threatening to leave if someone doesnt go, host would always be the one who gets to have fun doing space combat in space combat game mode.
As I mentioned before ground part of mission is too long, there is more walking(well parkour) then actually action.
Railjack game mode should be always first and foremostly focused on engaging space combat.
I am not against whole team going into ground part of mission but it has to be done better, like more to do in space than its currently, then ground section of mission that is shorter then currently and then another section of mission in space.
There shouldnt be any defense type missons ground missions in railjack(anythiing that is about players spending most of time waiting is bad), that destroys flow of mission, volatile on other hand is pretty good, its pretty engaging for players.
