These 20 levels sound more like DOW2 ranks rather than COH levels.
It's experience, not real level. And your level will only increase, even with losses, and even vs AI.
GuruSkippy is right. He is always right.
Only one post, but somehow I recognise that name...
OT: I think that the problem with vague bulletins is that they will not provide any big feeling of customization for the player, and at the same time they will be extremely niche. I'm afraid that they will only come in use every now and then and make you feel more lucky to have picked it than a part of why you won.
Example: You can't really tailor your strategy around 10%+ cover bonus, or 5%+ panzershreck accuracy, it's (arguably) too small a bonus for you to customize your play to any larger extent. If you do though get a panzershreck, and manages to take out a tank with a impressive long range shot, wouldn't you feel more 'lucky' that you happened to pick that bonus, than 'skilled?
