for roundabout, start by placing two wizards on the closest square to the entries and one warrior in the middle
then place four more wizards, two next to each side of the warrior, as close as possible
now upgrade: (I would only use fire)
mages: infect-slow-debuff (infect for those close to the entry), specialise them (specialism, inflictor, large increase...)
warrior: generalise as much as possible, and make him an archer
I hope this helps
