Cropping of Replays into short clips as attachment for reports should be a feature
Reports should include the game play of the player in question. I think we need a feature where we can crop replays into short clips 10-15 sec long that pinpoint the toxic behavior displayed through the player's actions in game and attach those along with the report that include the chat logs.
The game is evolved to a point where players can just say nothing but troll the game through actions alone that are undetectable through the system. Such as purposely staying in the jg to force your team to lose or just splitting and refusing to group to get your team to lose or take your team mates buffs or afking then coming back after a long period of time and claiming you were lagging or just plain feeding and claim that you are bad or ignorant...
This would avoid having a huge 40min - 1hr long replay attached with the report that Riot cannot obviously watch due to the volume of reports, and would go straight to the point. Allowing Riot to swiftly view the clip and deduce that the player truly had malicious intent.
Since Riot seems to punish intent and not action, I feel we need visual evidence to confirm a lot of players that get away with being toxic, stuff that cannot be detected with just chat logs...
Also if chat logs of the entire team were to be included it would show that the team tried to persuade the troll to play appropriately but they ignored the advice.
