The randomness of this game has made it harder for me than most people I think. I'm more than halfway through this game and my best tower is still my maxed out Wooden Tower. How early did everyone get Lightning/Dragon/Sun towers? The only rare tower I have is the Ice Tower and that does nothing if you don't have a lot of DPS to kill mobs.
My character is level 14, surely I should have more rare towers by now. I'm kind of stuck in progress. I can't do any of the maps now. Yes, even the Easy random maps are too hard. Also not at one stage was I able to do any of the Hard random maps. At what level did people stop using the Wooden Tower?
