So it’s a free handout, not actually grind-based.
Sandbagging in leagues is obviously an issue (though I personally don’t pla to bother with it).
I don’t think you’re doing anything to fixing it this way, and you’re handing out even more toons, when the game can barely handle the amount of toons as it is.
Because the game survives by getting people to spend on toons. If they hand out more for free, they either need to make them completely useless, which helps no one, or speed up the rate at which they increase the power level of promos, which is already crazy.
In the past they could get away with putting up lower variants of Promos, like red Zeke was a variant of Erika. But now that every Promo is free, this doesn’t really work anymore - Lots of people were happy with Zeke, because even a year after Erika was released they didn’t have her. We are no longer in that economy, so even absolutely decent free toons that would have been popular in the 6* era get dragged now.
I doubt it - I saw plenty people that I know don’t spend, even from lower factions and with midling activity (like 10k-ish points in CRW), end up in Platinum 3. It was very doable without spending and with only free toons.
