How to upgrade heroes at TH9 with regular clan wars?
I am going to TH9 as a max TH8, including lvl 8 walls, BK lvl 10 and lvl 2 Golems. Th8 was great fun but I am hoping that TH9 will be even better.
However, I am unsure about one thing. My clan wars regularly - we do about 2 wars per week, sometimes slightly more if the last war was too easy. I have set a target of getting my heroes to lvl 20 before upgrading to TH10. But I don't know if it will be possible to do that with regular wars. At TH8 it didn't matter as the dragons were powerful enough for most TH8 bases and didn't need the BK.
How do you guys do it? Any tips for managing it? I might be able to gem 10-12 hero levels over a period, but any more than that is just too much and not a good value for money, in my opinion.
