I agree with this, every party takes pokos and karmas because its really hard to do for example cc50+ without speed party, so other classes are literally useless expect u poko, karma, dende, or buffer (buffer with proper gear can tank so DWs and SKs useless asf -_- )
no its not really hard with no-speed partys, every random combo with a good healer and geared tank can clear ccbd just takes more time.
this whole speed problem is more a community issue anyway!
most people think like you " this is too hard without speed party"
i think most gamers these days just dont like to use their brains and test things,
they prefer copy paste item buildings, party setups and talents from better players and dont think about anything. ( not only in this game , in general)
with a better community this whole speed thing would not be a problem
but with players like that, speed need to be nerfed so people are forced to re-think their setups.
