NHF – new heroes for Heroes V 3.1.

Nura: Instead of 1 mana per turn for every three levels, make it for every 2.

I think the main problem is that mages already have enough mana. If it were a Town Portal, players would fight over it, even without any buffs...

Ora: 0.05 to 0.1 per level.

I think heroes who are already strong by default shouldn't be buffed (or should be, but only slightly). These are heroes like Ora, Hafiz, and Wingael... They are already strong.

Razaz: additionally brings golems every week, according to: (hero level * increase(9))/2

He's also a strong hero. Keep in mind that he starts with a lot of golems, which is a great bonus in itself. If you're going to add an additional golem increase, it should be significantly less (say, (hero level * increase(9))/8).
