Once upon a time a long time ago, healers triggered air traps… before I played COC! Now they will again in the proposed changes coming soon…

I am surprised by this planned nerf…
In a game where SPAM is coming to dominate the only real training for strategic play since you first get her is the HEALER. Yeah the QW is OP but in quite a different way to a SPAMMED bowler/miner army which is mindless OP! I like the variety the healer adds to the attack, a unit that has no attack herself… more of this kind of unit please!
But as many have pointed out the Queen Healer combination should still be doable, just not so OP, clever spacing of those air seeking mines to prevent QW! I was even thinking it may be possible to trigger them by sending out scouting minions… new nick name CHAFF!
Even if it does end up workable, here I is crossing my fingers, I still think it is a simplification of the game, another lurch to the dumbing down of COC… I am finding as I progress in the game (now on the road to maxing th9) that it drags and drags, if I hadn’t changed to a more active clan I would seriously be slowly letting my COC fall off!
FINAL WORD: SPAM is still the order of the day!
