Now, I know a fair few of you will mock me for this, but try to restrain yourself, because I think it's still legitimate.
Was Riot intending to make gold harder to reach so the victorious skins would be more exclusive (even though they were fairly so already)? Let me explain why this is the case, in case you think I"m crazy: The old system looked like this:
(B=bronze, S=silver, etc)
B5 B4 B3 B2 B1 S5 S4 S3 S2 S1 G5 G4 G3 G2 G1 P5 P4 P3 P2 P1 D5 D4 D3 D2 D1 MA CH
The new system looks like this:
I4 I3 I2 I1 B4 B3 B2 B1 S4 S3 S2 S1 G4 G3 G2 G1 P4 P3 P2 P1 D4 D3 D2 D1 MA GM CH
The number of divisions hasn't changed, nor the amount of LP needed within them. Really, Iron 4 is what bronze 5 used to be, mostly. The only reason this isn't completely true is because for the most part, only accounts new to ranked started there. Because the divisions are the same size and the theoretical amount of effort needed to move between them is the same.
Under the old system, Gold 5, the minimum threshold to earn the coveted victorious skins, is the 11th division from the bottom.
Under the new system, it is the 13th. Since player distribution across hte divisions hasn't really changed much, the minimum standard for Victorious is significantly higher, gold 4 represents a higher player percentile than gold 5 did on the old system- by two divisions. For me personally, I made gold 4 in Twisted Treeline (this is why I'm expecting ridicule) the previous two seasons. My peak this season was (breifly) Silver 2. Under the old system, I would have been gold 5. But now that's still two divisions away from gold. And I've just really been struggling to get there (But in part its because the champions I like to play aren't that meta right now =\ ). So it does frustrate me a bit that my best was good enough before and it isn't anymore.
Is this a huge teal? On the whole, I admit: not really a big deal (although it is for me since my performance would have earned me gold in the past and now it won't). It's just an observation, and I'm wondering if this specific consequence of changing the league structure was intentional or not. It's not as far off as I expected it to be because there are fewer players in Iron than there were in bronze 5-2 originally, but there is still a modest discrepancy.
(side note: yes i'm salty that I'm probably not making the cut for the final TT season ever, thank you riot for taking my love away from me)
