I agree heroes are worth prioritising.
Have to remember though a TH9 even coming from max TH8 start with a lv 10 BK and no AQ. Even getting both to lv 15 takes quite a bit of time and DE. You also have to find a lot of DE for the lab. Such as Golem lv 4 and today Dark Elixir spells too.
And then you have players who purposefully delay heroes to war more at full strength.
