New mod slice dropping rates

I've only been playing 6 months so not a true vet but mods are the single most frustrating thing about this game to me. They're so RNG dependent (not just finding speed stats but how much/often they increase) and this adds another layer of RNG to them. As a concept; slicing seems to be a good way of introducing 6 dot mods without invalidating 5 dot mods but this is just going to be ridiculous bringing one set of mods up to 6 dot let alone an arena teams worth of mods with the current drop rate.
