Set Giant Bombs to Hero mode
Obviously, everyone knows dragons are ridiculously overpowered at TH7 and TH8 levels. Some people will probably try to justify it for whatever reason, but with a dragon heavy attack (and lavaloonian on their TH9s), in our current 30v30 war our clan should have 90 stars in 31 attacks (because someone two starred a TH8 with 5 dragons and a lot of hogs.. hate it when people go against the formula!). Anyway, something that bugs me is that even if you build a defense against dragons and should hold them to one star, they can just drop their hero in after and their dragons will still have cleared out half the base (except maybe an AD that held strong), and the Barb King has a free path to level the TH and they get two stars anyway.
At this point, some will probably say something like it's in the game blah blah blah, but the difference between mass air attacks and mass ground attacks that makes mass air attacks even more overpowered is that in a mass air attack, they can clear out *all* of the relevant ground defenses and clear the way completely for heros. With mass ground attacks, I tell people they're stupid if they take a dragon or something in the CC because the opponent gets seeking air mines to blow up their dragons on the spot.. On the ground side, you simply cannot take out their air traps, but air troops can clear a way that cannot stop troops too heavy for spring traps.
How can we change that? I have a couple ideas:
Set giant bombs to "heavy" or "hero" mode, in heavy mode they will do 2,000 damage but ONLY be triggered by heavy troops, so hogs, wizards, and witches will go right over them. Further, the 2,000 damage will be solely concentrated on that one heavy troop, which basically creates a ground answer for the seeking air mine.
My other, more creative alternate idea is a hero snare that immobilizes a hero and drags him to a certain place of your choosing (maybe a 5 tile range). To save the hero, a ground troop that the hero did not summon and is not a hero must come to the aid of the hero and cut him/her free. The hero can still attack from the location he's snared at, so choose the location carefully as the trap will pull the hero to the center of the trap.
