because i dont want them to waste time typing to me if i have them muted, and i can get in trouble if i say it in chat, the same if someone mutes me. i dont want to waste time trying to call out a gank. only to find out my jungler has me muted
More likely this would just quickly inform them that they must use a different method to annoy you. Like ping spamming.
Telling someone they are muted in chat is one of those antagonistic things that just isn't a good idea, and you want to make it a system message? Use your pings whether they are muted or not.
Honestly this would cause the same problems as just telling them in the chat that they're muted (i.e. it would encourage them to rage/troll more and/or focus their efforts on making sure that you don't do well). You can still use pings to communicate with others, and by not calling out that you've muted someone not only do you encourage people to focus on the game more (and thus are not singling anyone out) but if someones already raging they'll eventually get tired of it when they realize that no ones responding to them like they wanted to happen.
OP You're asking for a notification of whether or not a player has muted you? (e.g. A black chat box next to Summoner name)
Sounds reasonable enough. There's nothing wrong with a graphical display when pressing "C" showing some way that a player has muted you. As well as receiving a system message notifying you.
You should also consider familiarizing with pings, since those can't be muted.
I disagree with the notion that it's antagonistic.
When someone tells me they muted me. That's nice, I guess.
