1) If you are going for the 3 star you cant do it with GOWipe. I have seen alot of Goho and some mass witch.

Now the argument could be made that they ♥♥♥♥♥ and practice hours to do those attacks, but in all honestly will you ever face on a 40vs40 war all max TH10 with dragonflower bases? NO.
2) A TH9 can 2 star a TH10 consistently, making it any easier would defeat your No.3 point, because a TH9 could 2 star the TH10 and the TH10 can be free to destroy the TH9s.
3) I never said I want an offensive boost, I think things are fine as they are. I can consistently 3 star mid TH10s and can get a 1 out of 4-5 on a near max one, and Im happy with that.
