hey i just got this and been looking around some guides and had some questions.

been seeing terms like IVs & Nature and i'm familiar with them in Pokemon but as for this game, does this mean that if two people have the same unit at the same rarity & level, their stats could be different? and there's nothing you can do about it? like in pokemon, you would just have a bunch of the same mon, then check all their IVs and then choose which to train. is it like that here? i think i also saw it said somewhere that the max stats for a unit are set but rng affects the level-up gains?

if i started training a unit and then later pull the same unit with better IVs is that basically wasted exp or is there a way to transfer the progress on to that better IV unit? i saw about merging but that is just a stat increase to the same rarity unit?

i saw that you keep around dupes for traits or whatever. at how many dupes is it considered "safe" to start sending home?

is there any point in training a 3 star unit? i know you can increase the rarity but if the unit has a 3 & 4 star version, it would be better to just wait until possibly pulling a 4 star? disregarding the chance you could never pull them again.

if i send a hero home, is there some sort of indicator to show that i once had them?
