Is it really worth it to get towers? Some say yes some say no? And how much defense is required? Do you have to have towers to war? And if so how much attack stats should I get before starting to build towers? All answers are appreciated!
the answer depends in what you intend to do. If you wish to EE, then towers are Important. Towers are good for most PvP stuff. If you want to strictly hit EBs, then towers won't be useful at all for you
ADT and anything less than 4M SDT are pointless for OSW. Depending on your build size 1-3M each is required for EE.
No, do not worry about towers at all. It's a common misconception that towers actually add to your defense. They're simply cosmetic to your stats and do not stick in battle. Plus, they reduce your plunder and make you pay even more.
If you like incoming hits so much, then you should look into joining a clan that participates in those tournament wars.
