Report characters max

I personally think that the report characters max should be expanded a lot. There are a lot of toxic and troll people in League of Legends lets face it and it's annoying that I can not write more than 4 sentences in a report. I like to go into detail about how the person was toxic or trolling and Examples of them toxic or trolling. I have run into the max characters countless times trying to fill out a report for someone who was toxic and I only got through half of what I wanted to say and the report doesn't make sense so I have to redo it. I think it'll make the people like me who do like writing longer reports and it might help rioters to get a better understanding of what the person getting reported did. Is there a good reason why there can't be longer reports? I would really like to know! :)
