What OS looks like the new way to get characters?

The new way of getting characters seems bad to me, because you need a lot of time to get them, it also forces you to play all modes when you may not want to play them all, I understand that TC wants people to play and be active but first I should listen more to community.

In my opinion I prefer to get them through similar tasks in Gears of war 3 or add them in a kind of Tour of duty, but the objectives that set the characters apart from being repetitive are excessive.
