Solmyr, Demeer, and Aislin are cheaters (and/or) kamikazes; do the rest have a right to exist?

I consider building a Town Hall in Heroes of Might and Magic IV to be equivalent to a ban. (Not in the literal sense, sorry if anyone didn't understand). Because you have to spend a lot of time building a Town Hall, taking a Mage becomes generally not worthwhile (except for powerful units like Solmyr with Chain Lightning and Demeer with Aislin and Meteor Shower).
