I've maxed my heroes at every town hall level and found my transition to be a good bit easier than a lot of people around me. The grind to max TH9 heroes, I won't lie, it sucks. Definitely the worst hero grind of any town hall level. Are you ready to upgrade? I am historically always in favor of maxing, so I say no. I would do as jawad9k suggested, 25/25 minimum. I would encourage you to wait for 30/30 though just because town hall 10 sucks bad enough when you first start, you don't want to make it any harder on yourself. Being a low town hall 10 and having to deal with infernos for the first time is extremely frustrating. Especially with low heroes.
