Yo skalla, nice to see you again.

I agree with you pretty much all the way, I think the tier system is an easier format for those who want to have more 'themed' battles

for example a swordsman fighting a swordsman, or some sort of warlock fighting a phantom with similar ability levels, and it also pushes some players to not just create demon vampire overlords who can summon meteors and do somersaults.

But its more of a optional guide than a rule, its there for people who need it.
