I have made this risky suggestion before, but I'd like to make it again here. I think it is very applicable:
The Matchmaking Engine HAS improved the game substantially, (though it will NEVER be able to do what players are expecting and demanding be done---NO artificial software script can predict a human player's combined performance and motivation in the next match, and pair her up against an "equal" combi-performance-n-motivation human player). Scotty HAS raised itself to a level where the word "matchmaker" is falling into our subconscious while we're in the gameplay, instead of being up front in our minds all the time (maybe in another year, it will be as forgotten in the background as Aim Assist).
So with a certain amount of comfort and elbow room put into our matches now, there is also room to restore some of the "Progression Difficulty" Dust used to have for new players.
What I mean is, hold new players back longer (MUCH longer) in Battle Academy. Get the WP threshold back up to a level where 15 year old addicts that spend 16 + hours a day at their fav games, can't burn through and unlock their Academy diploma too fast to really understand anything about the game.
A certain percentage of "new players" will always be the passerby type---they don't sit on a game that lasts longer than 9 hours to beat; they want to have fun mixing it up on a new title every few weeks--and kudos for them. If that type of player is properly quarantined in Battle Academy long enough, she will have her 3 weeks of fun and leave, without stepping into post-Academy and accidentally derailing our FW or Dom gameplay.
Simultaneously, players looking to stay in Dust longterm would also have the chance to benefit from a much longer, tougher semester in Battle Academy phase, until they've exploited the HECK out of every Militia item around, memorized how they work by heart due to the much longer repetition of use, learned the subtle differences of advanced gear mixed with their Militia suits, and start understanding the value of networking with older players via mail and forum, so they can prepare for the deep end of the pool BEFORE they're under the water.
Battle Academy needs to be deeply lengthened back to where it used to be, OR further. The "new" kids playing starting this game rack WPs at a rate that doesn't give them any honest Academy time.
