Why is there no system in place to punish these players? Why do we have to pay the price for someone else trolling?
Because there is literally no champion/spell combo that is 100% prohibited. If that nunu thinks ghost and cleanse are the best spells for him/her to support with, they’re allowed to use them.
Trolling is an act that requires action in game - as such it is generally impossible to troll in champion selection. Intent to troll expressed in chat in pre-game chat does usually merit an escalated punishment, however. Not a 14 day ban off the bat, but I have seen people get chat restrictions off of one pre-game chat where they threaten to troll, etc.
