I just realized the Iron division makes trying to climb way more grindy for bottom elo players
There was a Reddit threat that compared the ranked distributions of Season 8 to Season 9. One conclusion that was drawn is that the entire Iron elo is basically the same bottom percentage as Bronze V split into four tiers. This made me realize that if a player is theoretically in Iron elo, they now have to reach 100 LP and complete between 5 and 8 promo series to get into Silver. Some may argue that you shouldn't be bad enough to end up down there in the first place, but if someone does find a way down there, and then starts to improve, it would entail a pretty big increase in the amount of grinding they need to put in to get to silver than before. Mainly because promos are a toxic fucking coinflip unless you are so massively better than your elo that you're probably smurfing.
