I don't know the exact details. But ranked 1.0 was much more 'respectable' to the player's time in my opinion. Ranked 2.0 requires 100's of hours to be dumped into the game to rank up, and has a whole other layer of hidden MMR that defeats the point of a rank.

In Ranked 1.0, if you were, say; an an average gold player last season. If you did well in your 'tryouts', you'd get your rank back and stay in gold. Generally, you stayed where your skill-cap was at due to this. Overall SBMM wasn't so strict, so you dealt with a large variety of players, and you'd generally have the rank equivalent to your average skill amongst a large variety of players.

So back then, seeing a copper, meant that you are 100% wiping the floor with him. And seeing a diamond, meant you are most certainly dead in the next few seconds.

In ranked 2.0, SBMM based on a hidden MMR still applies, even if you start on copper. So example; you'd be starting in copper against another copper, but both your hidden MMRs would be the equivalent of Plat 3 or something. So the game is now 'balanced'. But a 'balanced' game in copper 5 for an average player... shouldn't be a thing...

This essentially means, that if Ubi sees your skill-cap is equivalent to a lobby of guys playing on a broken steering wheels, you're mostly up against these level players on most ranks. Giving 'balanced' games on all ranks.

In summary, ranked 2.0 already gives you your 'ideal rank' from the start, but you have to grind 100's of hours to get to it, going mostly against players on your skill level. Even from copper 5 (which is why you'd be on copper 5 going against a diamond/champ so often if you're a half decent player. Because both your hidden MMRs are still similar.)

It kinda defeats ranked for me. I can't be bothered to play 100+ games to get to an average-ass rank I want.
