The reward for reaching lvl 6 on Champion Mastery should be a Summoner Icon featuring your champion as a Poro.
Just look at them!

Lord Boltrix43 votesHow about, for champion mastery 12, they make it so that an actual poro follows you?

^This
Rew7114 votesWell, it took them a year to make 5 levels possible, its taken them close to 8 months to say they are adding two more, so in 2017 when level 11 comes out, we may have a slimmer of hope that it will be this in 2018.
But seriously, they've made a good 20-30 poro icons already for a different event in some other country. This idea wouldn't be hard to implement.

I'd pay 250 RP for that.

PopePancake4 votesCool idea

Stars Shaper1 votesAmazing gallery indeed xD

JustHippo2 votesI like this idea :)
Nunya Bezwacks2 votesI still think they should give you an announcer voice for your champion....but proods don't want it in the game since they don't like it so what can you do.
xFrostKnightx11 votesHow would you make profit paying voice actors for a free reward? What happens if a champion is reworked with a new voice?
The poro idea above is neat though.
Nunya Bezwacks2 votesdon't give me that bullshit one could say the same about the poro icon kid you're just another prood.
xFrostKnightx13 votesYou're just another idiot. Riot has animators and artists who are employed, this is why you are not forced to re-purchase the reworks. It technically cost riot nothing because these people are already being paid. Giving them an extra task won't increase the cost to have them employed. ie. "Assistant pick up pre-ordered coffee for the office", "no you have to pay me extra for that" Wtf??
Grow up kiddo. Voice actors are hired outside the company, thus they lose profit compared to someone they already own.
Horrow2 votesThe best thing would have just made Chroma skins (Though Chromas would have to be strictly for the default skin of a champ, which its already too late for) the rewards for high mastery level of a champ. Recolors are best served as a reward rather than trying to profit off of them. Its honestly a pretty easy way to appease your community. But oh well.
Sicksadpanda2 votes"GET BACK TO TOWER!"
"Why?"
"There's a Evelyn poro in lane."
Stars Shaper1 votesFor gameplay reasons I guess you can make Poros go stealth with the champion ;P
Awesome scenario anyway xD
Emperor Antares1 votesWhy as a poro...? We have enough poros, plus poros are so childish -.-
Stars Shaper4 votesPoros are the "fun factor" in LoL since the first ARAM map.
I'd like to see serious feature for level 5-10-15-20 and so on. These are usually the highest level you'll reach at any phase so inbetween you can add some funny and less serious stuff.
I don't know if it's doable but for the highest level of mastery Riot could add the option of a thematic UI like the one we see used by the streamers but that can be seen ingame and not just as an overlay in videos.
