Rebalance fans keep focusing on their subjective opinion of ''I like defense so it's great'' aspect while completely ignoring the objective facts i.e. effects this overblowing of defense has on the game.
So, to recap, by blindly supporting this (also not giving any suggestions to tweak this so you support it without condition) you also support:
- killing attack game variety and making only 2 compositions viable to even touch a base
- completely breaking MP in high medals and making only abandoned bases viable to be attacked to sate NTG and diamond needs.
- complete p2winization of the game, before you would need the overpowered troop cards to get fast times (and even then Impi from Marco troop chests would do very well) now you need them to even have a chance. Also shortages of troop cards (mandatory now for every equal age attack) unless rubies and Marco Polo troop chests are increased
- making the game in wars and MP unplayable for casual players who don't take the time to analyze every troop, test compositions, tactics and strategies. That is the majority of the playerbase like it or not.
Finally, as hard as it is to admit for folks like you, this is an attacking game. The active part of the game is attacking. Defense is passive, the computer does it after you set up your layout, and the best layouts have already been found.
You make attack boring by either making you wait for retrain times of tactics, generals, planes and costs of mercs, or make you attack only rushed bases which becomes boring, or in the case of casual players make attacking a nightmare and make them useless. The end result is you make the game boring. And people leave.
