Reduce GW's Life Aura Ability max to 35% or please release lvl5 giant bombs for th10+

I am a titan 2 Almost max Th10 player and I am seeing over whelming of easy 3s attack by TH11 using bowler back up with healer even when i change my base a few times. This scenario is not common for th10 attacker with mass bowler because of the lack of Garden Warden.

With Garden Warden life aura ability, Bowler hp is 555. it is not killable with double giant bomb and it get back full health when healer just keep healing them. With eternal tome ability, it should be fair to reduce bowler resistance to good giant bomb placement and slightly increase the challenge in order to get 3s.

by reducing Garden Warden's life Aura ability from max 50% to 35%, it should be cap bowler HP offset at 500 which make it killable with 2 giant bomb. Alternatively, please release lvl 5 giant bomb for th10+ for total damage more than 600 to make mass bowler play a little more challenging. I don't see it is a strategy game play for th11 to easy 3s most th10 without much game plan
