Mixed Special, because an Electric/Dragon type can hit harder from that angle, and has powerful options for support, like Discharge.
It doesn't necessarily mean mixed offenses. I have a spread I'm working on with good Physical Defense/Special attack, which fits mixed.Special. stop bandwagoning and think about your vote guys. a defensive pokemon (even if it's balanced) has no reason to go mixed. have you seen mixed celebi? how about mixed skarmory? the only exception is swampert who only runs earthquake cause it hits electrics for more than earth power.
and if you are gonna jump on the wagon, pick the good one.
Which is why I'm pulling for it to be a Physical Defender and Special Attacker, as opposed to the reverse.
Since this CAP is supposed to be Slightly Defensive, I think it would be better to have higher defenses that attack, but still give it the option of going either way.
And to re-enforce my point, Why do we need yet another physical Attacker in a metagame that's already physically focused? Adding a new special attacker brings diversity to the game.
Not to mention that most of the current physical pokemon don't have a spectacular special defense, meaning that a good special attacker can take them out. If this pokemon can take physical hits, and Use the Special Attack stat well, then this pokemon can do it's job well.
