You'll find many opinions on this subject, I know most Tower build owners love their build and will defend it in forums or wherever. I know most that have faced one either in EE trials or OSW are not fans at all. And lord help you if you have to face a clan of them. I don't think people should be punished for using them, no matter what has happened in past Joe_. But I do agree, they throw the balance of the game in jeopardy. It's like playing rock, scissors, paper, and someone throws out Steel. The amount of effort it takes to pin a Tower build could be spent pinning 4 of almost any other build. That being said, I happily recommend any clan mates directions on how to build both Attack, hybrid, and hansel variations of tower builds. If you can't beat em join em. But it will bring back a variation of turtle wars that I don't look forward too.
