Ranked 2.0 Changes Leaked (Subject to Change):
No Bots (Even at bronze)
Leaver Penalties (resets every month, starts with 5 minute ban from matchmaking, doubling each time you leave)
Previous Ranks Affect Next Seasons Rank much more than before (IE if you hit Unreal in the previous season you'll at worst be starting in Elite/Champion, this is to prevent Lower Ranks being constantly stomped on by people moving up)
More Rewards (Seasonal Ranked Skins brought back)
Ranked Blitz
Zero Build Ranked Potentially Getting Vehicles added back, but kept out of Build Ranked

Everything else is minute stuff nobody cares about.
