You call ELO
"a chaos of luck, a maelstrom of nooby proportions" (kudos for the poetic language, by the way) ...yet you mention hitting 1500 several times.
Now, let's quickly go over the facts.
-UR is a card game.
format has 8 card decks, with unequal star counts that must add up to 25.
-A 5* card is, as a rule of thumb, going to be significantly more powerful than a 2 or 3* card.
-Your opponent may not draw the same number of stars as you, may draw cards without bonus, etc. This gives the game an inherent element of luck that *has nothing to do with the meta.*
I'm more of a 1350-14xx player, myself. I know from experience that the best way to get to 14xx without grinding for the entire week is to pull off a good winning streak, or at least a set of games with a very nice win/loss ratio.
So... To get to 1500, you not only need a large set of games with a very high win/loss ratio, but you must achieve it while matched up with some of the best players in the game. You are fighting great decks in the hands of seasoned and skilled players.
Let's try to get this straight. Do you REALLY think that something like a 10-game streak against the best players in UR is "good luck," and that if you handed some 12xx player your deck and gave him enough time, he would be able to do the same? Because that strikes me as an absurd conclusion, which disregards statistics in favor of personal bias.
I think for 1400+, luck is optional, but skill is mandatory.
