I'm sure if and when they add an 8th tower it will be like any other "update" or addition in Graal. Everybody and their grandma will be fighting to control it because its the new thing then after like a month or 2 everyone will go back to complaining about being bored and waiting for the next thing to come out.

Don't get me wrong I'm all for another tower,maybe its my OCD and wanting the # of towers to be an even number.
