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

Besides Galtran, the Necropolis faction has good heroes like Clavius, Tamika, and Isra, whom I would prefer over Tantu. He is only effective on a map with abundant resources.

Cobra has played many games with Tantu:p, and won them all (or has a clear advantage).

If the opponent is much lower in skill level, then with a normal starting setup, you can win by playing as any hero.
