Game too complex or easy?

[Intaki]

EX primals were alwys hardcore content in 2.xx.

I really wouldn't call Shiva EX or Leviathan EX hardcore. And the rest of the EX primals were only marginally more difficult than those two (save for Ramuh, maybe). They were hard enough to be challenging to the average player, but easy enough not to be impossible. If that's not the definition of "mid-core" then I'm really not sure what is.
