I'm pretty sure Pekka 4 will be available for th9
I know SC try to temp us to go to TH10 ASAP, but all that candy for TH10 and nothing for TH9 latest updates is one step to far. The gap is about to get to big and they know it. After all they try to find decent balance over time.
It's a good time to remove that "can't heal from ITs" now when hogs die on Giants and central Heroes. Would help the balance a lot, I think many TH 10 guys think so too. Some wars 2-3 top players are untouchable, that's boring for both sides.
