[HoMM3 on-line Tournaments] Arena "Will and Reason"

and in TE, there are arenas where you can place already existing heroes from saves, which would generally allow you to reduce the game time to a minimum:D

We don't need either "TE" or pre-made heroes... it's interesting when there's diversity...
... those who want to reduce the game time to a minimum can simply create another tournament and borrow ready-made rules and a ready-made template (which Raper mentioned) ;)
