Maybe I just need more coffee, but I'm not understanding how the new point system works.
As an example, if I get Rank 7 with 3 kills and 2 assists....
Rank 7 = 20 RP
Kill/assist Multiplier = 12x, so does that mean I combine my kills and assists (5) and then multiply that by 12? So 60 RP for kills/assists + 20 RP for placement = 80 points for the match?
Or
Since everything is multiplied by a factor of 10, each kill is worth 10 RP (instead of 1) and then only your assists use the multiplier? So in my example, I'd get 30 RP for kills + 24 RP for assists, making my point total 74 for the match?
Your first calculation is correct; you will earn 80 RP for that match. We probably should have said this more explicitly as well but the screenshot of the in-game HUD shows how this math works. What might not be obvious is that the "+32 RP" takes into account the entry cost for you, so in that picture it was: ( 2 kills + 1 assists ) * 12 + ( 20 from placement ) - (24 for gold entry cost ) = 32. Yep, we know it's a lot of math; the hope is that with the HUD element you can just take a quick glance and figure out what your RP change would be at any given second.
