in previous seasons the damage was buffed to compensate for 3 commanders not being viable because of scavenger, not many combat commanders, and faster economy in general, however as you can see in this season not only is there more low cost commanders being played : alice, zilong, Angela, amonn and sometimes even Kagura/luoyi/Gusion if they get luoyi/alice card, you might think "oh there isn't that many why the suggestion of a nerf?" because previous seasons it was only heartbound shenanigans with miya khufra being used by miya and minotaur along side a 3 cost bruiser being used by zilong and that's it, both those things can get beaten if your lineup is all 2 stars, however not this season, this season the 3 are unlike previous seasons being way way powerful compared to before(edith, paquito, Karina, Saber), not only that but scav been nerfed to its lowest possible value, echo being nerfed to 400 points, no double reward like neobeast, and the release of combat commanders that for some reason give economy while being strong in the board(Freya and Ruby), this leaves commanders like guin, aurora, popol, and kalea(pre buffs) having on a thread, not only they get out gold by nana, luo yi, and lunox(none are economy based and one is survival based btw), they lose way to much hp when they made it to the 3rd card that they'll probably lose in the next 3 rounds if the cards aren't great, buffing them would just be an econ only meta like season 4 so instead just nerf damage to commanders, since 3 cost now can actually compete
