After playing with Cyrax alot yesterday, let me tell you, do NOT go for the B3 net combo outside of a direct punish.
You'll try and wiff punish a button with B3 -> Bf1 (cancel), B3 -> Net and the Net won't link due to the travel time. This link only works close up, in the normal range of B3, not as a punish for any wiffed button. You need to go straight into B34 after a canceled B3. Happened to me so many times yesterday. So frustrating.
After two days playing the character, it feels like his AA options kind suck? and anything punishable that's outside of B3 or F1 range still goes unchecked. So he can get abused by otherwise risky moves.
Still lost on what Kameo to play. Cyrax is ok due to throw combos and punish damage. The meter drain from Net is insanely broken. I feel like you miss out on lots of little conversion that Scorpion is able to pick up though. Stryker seems boring but could help his neutral. I agree that Sub doesn't feel real, more of a counter pick to zoning matchups maybe.
