Duel Tournament will be played somewhere in between 20th of August - 15th September. Duel is played in colosseum map (Turalyon / Dwarfbier can modify RB server and make it colosseum for a while where we can have some duels). If you ask when is the tournament? -Tournament is always ... I will post here a ladder, where who against who plays - those players who already have an opponent will take 20 of their minutes and go together in colosseum to play 10 rounds + When duel is finished, both players make a screenshot of the score and send it to me on email@example.com with text who you battled and who won.
If anyone wants to have a mage duel, post here, and if there are enough players, we will make a tournament out of it.
Your reasoning is excellent -- it's only your basic assumptions that are wrong.
