I've found TH9 to be much more difficult to gain loot than I did TH8. DE is easier to come by but gold and elixir is tough. I think TH10 will be even tougher. If you think it will get easier with a TH upgrade then I think you are mistaken.
If your lab is finished for TH9 (barb 6, archer 6, loons 6, minions 5, wall breakers 5, wizards 5, giants 6, add gol witches and hounds if you war) then go ahead to upgrade.
You are prey to TH10s as it is so upgrading while still preme on defense isn't that big a deal. Don't handicap your farming (by removing TH8s as a source of income) if your offense still needs work.




My base wasn't that bad in defense.
