For one thing, it's not needed. I created a new account about two months ago. I have raided with it one time and done two war attacks. Just sitting there is already near max 5. They key there is I have not raided with it. It's just a place holder to be the leader in our feeder clan.
It takes no effort to get to TH7 and it takes only a little effort to get to TH8. On one eight, I maxed it in six weeks and that was before clan games and the trader.
You can easily be a TH9 in two and half months if you raid. So raid and stop being anything below TH9. You won't get anything new there either but at least you can start that long hero grind at TH9.

TH10 may get new stuff for a little while longer but soon it will no longer get new stuff. Actually, it may have seen the last new thing it will ever get.
