I agree and would love to see the actual number of points removed or at least have the option to hide. I like to play casually, a game or two at night after work to unwind. However, after 10 years of that, the mastery points really stack up and this always leads to taunts and troll-speak from my team and the opposing team. Yes, I can and do occasionally mute, but it is still an annoyance.
Also, playing a top main is hard enough to get a jungler to gank, even through I always set it up with a pushed in lane...it is MUCH worse with the high mastery points as it gives the jungler another reason to ignore you and leave you on an island.
Yes, I know that I just have to adjust my game play when these things happen, and I do. It just would be nice to have the option to hide the actual number to remove this annoyance...and honestly, that would be such an easy thing to fix. Thx for the consideration.
