I love Missile Assault and agree it needs more players and love.
However, I have some disagreements with both the point and sentiment behind the OP's comment that, "it's the best mode which really empower individual skill and decision making while also letting the weaker players contribute instead of ruining (no feeding)"
Sorry, "No it isn't." Missile Assault is even more about teamwork than any other game mode. If a player is trying to rely solely their empowered sense of individual skill and thinks they can take and hold silos fast enough to foster a win, I think they will usually find themselves headed for a team loss.
Missile Assault requires a great knowledge of the specific map and the ability of an entire team to rally towards exploiting the strengths and weaknesses of each map. Each map generally has two silos which are the ideal silos to hold and one silo which it is better to intentionally give to the enemy. Take "Last Eco" for instance: your team should be striving to hold S1 and S3 at all costs and avoiding holding S2. 1 and 3 are easy to travel between and, once held, allow control of the middle/high ground to keep the other team at bay. S2 provides terrible spawn points which are too exposed and require a great deal of travel, across dangerous terrain, to get to either 1 or 3. So, if you leave S2 to the enemy, they are stuck with crap spawning and have to try to escape under fire.
It takes everyone on the team cooperating and being willing to "hold" their position. You have to get three guys to commit to working together at S1 and three guys to commit to work S3... and you have to hope you don't have some Rambo ruin the entire plan by taking S2. The moment you have S2, the other team starts spawning behind S1 and S3... and your plan is ruined.
I'm not saying that having a great player on the team can't be a huge asset, and that it is more complicated than the strategies to win a Siege match. I'm just saying that "teamwork" is the most important part of Missile Assault.
