the solution is everyone jumps ship to servers uninfected by ffcd
the issue isn't just that it's strong, there's also the fact that with stronger and stronger stuff being made there needs to be stronger and stronger dungeons aka power creep which makes everything that's not being buffed shittier and shittier
also makes the game more about buying shit from the rem cause the old stuff becomes obsolete.
like way way back in the day all you needed was a good leader like Kirin or Luci and then you were set cause all the optimal subs were actually farmable (heras, echidnas, valks, etc).
then they made awakenings which made the other rem monsters viable as subs but made farmables shittier in comparison, which was okay.
but then they started giving some rem monsters much better deals than other like max awakenings and TPA stacking which makes other rem monsters who got terrible buffs shittier in comparison.
so then when they make new dungeons with bosses that have more and more hp the weaker cards are left struggling while the stronger ones blow through them with ease.
i mean tbf gungho is still way better than a lot of companies when it comes to this stuff because they actually buff old cards but this kind of jump just seems to set a bad precedent.
i guess the power creep already started with ronia and friends though.
super biased case in point is Isis. back in the day she only had x3 so she was generally considered a shitty horus and struggled to deal with most descends. then they buffed her yay she can clear descends now but her subs still suck lol have fun with bubblie and sieg while kirin has apollo and izanagi for melting faces. and the finally now isis gets some better subs with muse and super bodin but at the same time oops we also released much more powerful cards and more powerful dungeons to go with them like god rush and true final super ultimate for realz this is the last one endless corridors and Isis is struggling again lol oops sorry you should just switch to ronia already.
also making a ronia like ez mode leader stronger than anubis is dumb i mean come on
