We need an Official Replay System
If someone use's third party programs as replay systems, And imagine getting reported for cheating just because you outplayed someone and they'll say you are scripting, Instead of the system doing nothing because you aren't scripting but they'll detect the third party program aka the replay system and will ban you.
Riot is never nice with Third Party Programs. If you use a custom skin and have Mojo program running, You'll get banned. This happened many times to many players getting banned for using Custom skins.
Can we please get a Official Replay System, Because it's been 7 Years since LoL was released, And LoL is the biggest game in Esports. Please release a Replay System when the new Client is ready to be released.
