Game was already imbalance b4 the addition of lvl 11-15 dominion, and guardians. With these 2 latest inclusions, the balancing is way too screwy toward the coiners and the attackers. Basically your Coa are fools if you want to hold some pantheons. Even if you have strong federations and diplomatic ties to back your Coa, it still too damn risky and unadvantageous to hold pantheons and even defending your coa capitals.

I witness first hand how pantheons and capital falls in a very unfavorably way. One coiner send an attack of only about 100m offense, but since he got a very powerful G5 guardian and all his offensive buff activate, he manage to clear a whole pantheon stacked with over 250m defensive strength. Now those of you trolls out there probably reply "Well, if the defending coa activate all their defensive buffs and send all their guardians to the pantheons, that wouldn't have happened".  You can't always activate defensive buffs it'll cost too much and not everyone can afford to send a top grade defensive guardian to every pantheons his coa owns. The lvl 11-15 dominion also give attacker up to 25% additional buff.

People keep saying defender always win, well not anymore. Aggressive coiners alway win. I understand this is the way plarium wanted- to generate more spending from coiners, but it terribly shift the balance of the game. Those who read this, tell your Coa hegemon he's a fool if he think defending pantheons is a great idea. Might even think about not defending capital. Sure your Coa can hide behind a big Federation and have strong diplomatic ties to back you up, but it's still risky and it ain't fun to play like that. Like a bunchas gangster waiting for a new kid on the block to bully.
