"Normal" is completely arbitrary in that it is based only on what the community expects/considers standard. Breaking or not breaking the normal rules means nothing because the rules can always be altered to whatever the people want them to be. For example, the only reason that Cults aren't normal isn't that they go against the normal rules, it's because the community has decided that Cults generally suck and should pretty much only be seen in specialized games.
Does the community at large think that
hydras
generally suck and should pretty much only be seen in specialized games? Probably not, but there's room for debate, hence this thread.
Perhaps a poll is in order? Although, you'd only be polling people who visit MD, so there would be some bias. (I would guess it would be against hydras.) The mods could make it a global announcement, but that's purely up to them.
