You don't have to remind us constantly that the population is down on PC. Clearly it isn't rocket science to visit a webpage or look at our own analytics and see the same thing you are seeing.
Techically, it is not down. The same people still play in the same days or time which they play before. They just don't grow.
I'm also still see new players (not smurfs) in low tier lobby (I mean, people still come and try to play), but here the problem "1 day hawken". It's mean they try to play, understand (or don't understand), how it working, and leave from game by different reason.
It is sad, but I should say that you (devs) still don't do nothing to trying solve this problem, understood how game working, and analyse this. To trying "keep player in game" (I don't mean increasing grind, and mech-tree. Because it can be reversed effect, and also restrict mech choice for player, allow everyone play only on tv and assaults when player start play (I mean, matches 6 CRT vs 6 CRT)
No any freebie action (like in MWO for example), where you should do something, and got a small reward (lil piece of MC, special event-camo, which dissapear after time, or maybe be a prize for everytime). Maybe, special reward for nubs if they do something, well, you know, you give player not zero-account and say: "pay me right now!", instead of this you give him try some things, which allow player love his account, love his mechs with camo, and then they think: "meh, I want more!". And buying camos/chassis, for their favorite mechs. It is like a drugs, and you like drug-dealer. Just my personal vision. You should give something, than take something.
P.S. C05, can you thinking about idea allow players change mech bodies on consoles?
Sorry for my eng.
