meyybearodactylpocket or roamer is a role, not a class. regardless, this is an issue because of the john milter theory where u pick ur medic (mr popo) on scout and just switch with him. a specific pug where rocket got picked on scout and sandblast on medic comes to mind, doesn't that seem a little unfair?
John and I had to switch a couple times because he forgot he didn't have a crossbow. If someone is captain they can pick themselves on any class so what does it matter? You think the other team missed out on the mr popo medic x-factor?
We should ban captains from selecting their own class. That way they can't decide to pick themselves on their main class and throw off the balance of the pug. That's effectively what you're saying.
