I need to suggest some QOL improvements

First: An ally has been slain An ally has been slain.. An ally has been slain...... Killing spree! An enemy is godlike! An ally has been slain!

Can we filter the announcer to cut this sh*t out? it's hugely tilting. Yes, I know we can lower the volume of her but we also lose other key soundbites.

Secondly: We get a border based on our level but can't select previous borders....what if we prefer a previous one?????

Thirdly: PLEASE! let us hide our mastery points!!!! Either one of two things happen if you have a high MP....

My team feeds and blame me for not 'carrying'

or

The enemy jungler pitches a tent top lane and proceeds to camp me all lane phase chunking me for 2/3 my health every gank meaning I have 0 impact on the game.....and my team still feeds.
