1. People getting stuck on everything. Seriously?
Not sure what's the reason for it, but I'm going to assume, you have like laziest level designers in the world. Here, I've got a picture of them creating new maps for us: http://www.steadyhealth.com/130736/Image/kids_drawing.jpg
Mates, you don't need to create new maps, just fix the existing ones. Quake tournaments played on like 1.5 maps for 15 years, I'm pretty sure you've got the quantity covered already.

2. Why did you bothered to include the KB/M if you're not going to let us use it anyway?
After playing years of different FPS, I was very excited with Dust supporting mouse and s***. I even got my PS3 out of the box to play this game. But last week, I've spent more time tinkering with controls, sensitivity and Logitech's SetPoint, than actually playing the game. And you know what? I'd more likely eat my dingleberries for the next month, than play Dust competitively for another week. But since Dust is a lovely game with a lot of promise and I don't want to stay behind, I take every battle very seriously and guard the MCC's drop bay to make sure noone enters from outside.

The idea you have behind balancing classes DOESN'T WORK with mouse and keyboard on a table. Soooo many games pulled this off. Crippling KB/M controls to eliminate the advantage before DS3 is the stupidest idea ever. Like borderline idiotic. EVE is a competitive universe and it should be up to players to select their weapon of choice. I always laugh when hear DS3 users complain. It's like watching my mom complaing about burnt dinner, while she was watching TV and not doing s*** in the kitchen. Cmon, mom, put your s*** together and make me proper dinner.

You have two options, I think:
a) Give KB/M freedom it deserves and was made for. For example, you can be much faster in racing games with steering wheel controllers, I don't hear people complaining about GT5 supporting them. Gamepads are great for mario and nhl2013, NOT for FPS.
b) Remove KB/M support completely. People like me will probably leave, but who cares? Plenty of people will stay and play casually.
MAKE YOUR MIND CCP!

3. On-boarding and matchmaking experience is terrible
I can see many reasons for you not resetting the SP after launch, you greedy grinch. But new people are choosing not to continue playing, because they are getting raped by someone with 20mil SP every 25 seconds or so. I've gotten out of the Academy after playing just 2 evenings in a row (I'm not a bad player, topping the leaderboards quite often). Since then, I often join games with two very strong squads from top corps playing in one team and bunch of random losers in the other. That's when I usually decide to guard the CCM and do some work. If I wouldn't be an EvE player, I would left the game like tomorrow.

4. Imbalance due to Beta characters
Again, I can see many many reasons behind current position, this may be solved with better matchmaking, and I'm sure it will be at some point. But according to my calculations, I'm gonna need at least 6 months before I can actually hope to kill veterans. Or 3 months with $200 and a lot of time investment.
Okay, at this point I'm just going to ask: seriously? I'm sure you don't want beta players to leave, but new people will NEVER catch up with them. Couldn't you like issue some blueprints to beta testers? Just to avoid new people feeling useless for the next 6 months? Oh, you don't need new players? Oh, screw those newbs! Gotcha!

5. WTF with vehicles killing people instantly?
I mean, yeah it works like that in real life, but man, I've got shields and stuff. I can survive a freaking shot to my head. Why am I getting killed by a buggy? It's not Carmageddon, man.

6. Why is everything so expensive?
I get it, you need money, and PSN got some expensive stuff and TBH, I'm a working man, I can afford it. But man, I'm not gonna spend $100 there. I'm not even going to spend 10 bucks, I'd rather eat them. Because it's just too much for nothing. But I so would buy tons of stuff for 3 bucks/piece. Read 'How We Decide' someday.

7. Who thought of making black dropsuits and green scopes?
Or TAR's scope muddy green? What is it made of Sprite bottle? That's the future I'm hoping for: immortality and weapon scopes made of sprite bottles. Color diversity is great, but you gonna have to either make all of suits bright, or let us custom color them.
Did you try to shoot someone in proto suit standing in the shadow through the scope of TAR?

8. Can you put sofas in the drop zone of MCC?
I just want to sit down for a year or so and wait till you fix all that.
