Overreacting? If you go to a car dealer and testdrive a Merc for a week and decide to buy it and the dealer decides to exchange it after a day with a Yugo, would you be happy? The dealer will tell you, it is also a solid car, just not that comfortable. If you answer him, I either want the car I had tested and bought or my money back, are you overreacting?
And they are still very solid towers: these are my FB without the nerfed boost also, no need for the boost anymore. I was just beaten by a player 11 levels below me with just knights (!), something the version of the towers we bought would have made impossible. Sorry, but the boost is useless now, no way we would have spent the gold for it.
