As someone who personally maxed 30/30 heroes, I would say it's not necessary. Dark Elixir is much easier to come by at TH10, so unless you're like me and are dead set on getting 30/30 heroes at TH9, don't try to max them.
Agreed. And if your gold and elixir storage are full while you try to max heroes, you’ll end up wasting a ton of resources.
