Hello X-Tasy -answer for your question
Evidence number 1)-Look at the latest KS updates there is no mana bar at all (#47 #48) pay more attention for heroes portraits there was ONLY Vitality\Health bar. Below you can see the link to Russian site if you know Russian then you understand that there is no mana bar! Reviewer wrote exactly like this about absense of mana bar and he thinks that it`s one of digression at old-school games . Don`t be fooled by screens it was from earlier build of game

And Even at KS comments section someone noticed that mana bar was disappear.

Do you see the difference?
And of course there you will be able to cast spells but with restriction of cooldown period only

but this idea can be used ONLY if money would have weight.

BTW what do you think about money weight ?To be or not to be? devil
