I read this before I bought any classes, and it was very useful. I now have Hammerer, and I think I will buy an orc class on Erebor next, since out of all the maps this one seems to have the most OP defenders to attackers ratio. Any other suggestions for what I should buy next?
Buy Royal Guard. Helmsdeep is a map that gets played a lot, so I suggest buying classes on those kind of maps.
