Why rush removed from game?

Rush can be run only 6-7 days in month, only from Portal mode.
This looks like cruel bullying.
I previously played BC2, BF3, BF4 - always only in rush mode.
What should I do now?
Play COD?
Okay, I won't play your games anymore, that's all.
Keep losing customers. Moving right way.
