once I start dividing champs into attacker, defenders, cappers, etc-- I'm starting to see how large a problem rammus/singed can be when they play as cappers
Only counter I have seen/use against rammus/singed so far is to either outcap them or just pile a couple champions on them
Most of the time, piling on top of singed/rammus is a bad idea. Outcapping them is usually the better idea but is very champ selection depending. You'll need not only to build dedicated capping items but also dedicated capping champs, like eve.
