ARENA LP UPDATE

ARENA LP UPDATE (reload the app once to install) 
Arena LP now scales with who you fight — your hidden MMR still drives matchmaking; only the LP you gain or lose changed. 
What changed
Beat someone around your rating → normal LP (~20 on an even match)
Beat someone rated higher → bigger gains (up to +30)
Beat someone much weaker → small gains (down to +5)
Lose to someone much weaker → bigger LP loss (up to −30)
Lose to someone much stronger → smaller loss
Master, Grandmaster & Challenger now show LP on the leaderboard (e.g. 2,212 LP)
