There will be tokens for weapons from raid. But weapons aside, there will be less loot and smaller loot tables in Shadowlands. Removing bonus roll is not punishing anyone with bad luck, it's the opposite. It's punishing those with unfair luck. Also having loot tables smaller (and no duplicates in one chest) means that the rng will be a lot better than with M+ chest in BfA for comparison. It's also worth noting that gearing changes in general in SL. Blizzard wants everyone to gear slower. You won't get your BiS items as fast as you did in BfA, but nobody will, so the playing field is even.
