What does experience have to do with it? It adds independently of the hero.

With the health bonus, there was quite a story – in the fixed maps, everyone played as mages, so Horn, during the development of the Town Enhancement, strengthened warriors and weakened mages. The health bonus was invented precisely for this.
In random maps, the task is reversed – to strengthen mages and weaken warriors. Therefore, the health bonus can be removed; it doesn't add much in terms of strategy. Heroes like Shahti, Galtran, or Taras will be perfectly fine without the bonus, and other heroes will have a better chance of becoming powerful.
Otherwise, why take the WATER skill.
The only thing is, yes, something needs to be done about Bronghild, he is way too strong. It's not just ducks he has, they're some kind of prostiDUCKS.
Well, and how to boost mages? I personally don't understand..
Agreed that most of the rules are built into WT. Only things like red-rush and shifted guard remain. The other bans, like unit upgrade for Conflux and Dimension Door — it's clear that these are all allowed.
