Yampi,

A] There will be multiple pools since I am releasing the pools open source
B] The Hashing Channel will break Prime Channel streaks and vice-versa
C] The Decentralized Checkpoints only allow the Main Chain to be built, not overwritten.

All this being said, we don't have to worry about 50% hashrates anymore. Each Feature reinforces the last to secure the Coinshield Network.
