The tough ones are getting stronger if you upgrade them. I don't know if it's possible that there will spawn more tough spiders/zombies etc. with upgrading the spawners. You will receive more exp if you upgrade the spawners though. :)What is the best level to have a spawner as high as possible so that "tough" monsters do not reach level 15?
