All we know what defence team has +20% to attack by default. It’s not indicated in the game, but it’s fact. As I right remember SGG argued it with something like “human more smart and defence team must have privilegie”. So, for example, my GM in attack make burning damage 203 and the same GM with the same parameters in defence team make burning damage 243. Cool, right? In my opinion maybe 2 years ago it had any sense, but not now anymore (especially after Telluria’s release). For this 2 years AI of game (PVE) become more “smart” - they CAN and DO HIT exactly those opponents who are needed, while the player must seek for combinations of shields on the board in order to inflict at least some damage. Of course, board can be on your side (lucky board), But after the release of Telluria, the player’s dependence on the board became too big.
So maybe it’s time to remove or change this defense team privilege? I saw similar topic in past, but can’t find it now.
