Title This has seriously cause tons of trouble for me and it happens so often. Pick intend is more than often unused, and when they are used, players tend to not look at their teammate's pick intend because they are used to everyone not using this function. There had been so many times when someone's pick intend is banned by their own teammate, and they raged and trolled.

Deep Terror Nami1 votesI don't really care much about this topic, but I did have an idea about it anyway; just have Pick Intent champions outlined in red on your list.
Lycanoon1 votesIt's called being STUPID!.. People who ban intended picks, are just douche nozzle's used by Hollywood tramps after a night of banging the entire town.
Oh, is that offensive? Not as offensive as someone banning your intent pick... So...

PiVoRx1 votesJust prevent from banning intended champs, more people ban their team mates on purpose (force dodge, troll, etc.) than by mistake.
