Well, i had the opposite happen in my races man.
Just raced Vertabray before, in 2 GPs.
FIRST GP: Armada 3 Bray 1
RACE 1: I won.
RACE 2: Bray won.
RACE 3: I won, was a close one, Bray nearly hit the line here.
RACE 4: I won, after getting a Blue Shell followed by a red on the last lap to catch him (i'd fallen off and was a bit back).
SECOND GP: Armada 2 Bray 2
RACE 1: I Won, fave course, rainbow road.
RACE 2: I won, i got hit by a blue, then i got a Shrink Cloud (which speeds you up dramatically till you shrink) but managed to wipe it on the cannon, then copped another cloud, didn't catch Bray, but then got him with a blue, then another red (like before lol) and managed to beat him by a corner or so.
RACE 3: Bray won, it was pretty close for most of the race, but he made good placement with his bananas, making it hard to get through and slowing me down by a few corners at least.
RACE 4: Bray won, a mirror course, yuck lol, we both did silly things, like hitting the caterpillars, falling off, turning the wrong way, but in second my best was a red shell, and then a mushroom, which i used brilliantly going off the edge lol. Bray won easy.
I don't think 1v1 is broken at all, i was in second multiple times over all 8 of those games, and only one game did i get the cloud, though it was twice in a track. Another game, Bray got it, and passed it on smartly to me, just in time for me to shrink, very smart. The few times i did get it, the game gave me blues or so on, to even it up. Most of our games, we were both in it right till the end, with the exception of 2 races, one i caned it in, and one bray caned it in.
I watched your races with Charelle Beatnik, only from her point of view that is, and i think what killed you more than anything in the 3-1 loss, was she got some good items right at the start (cloud she got passed to you just in time to shrink you) and after that you struggled to get back in those races. While, the race you won, you won solidly.
The game involves some luck, so sometimes you'll get blues galore, other times clouds galore, other times nothing but crappy green shells or ink. That's how it goes, i take my luck when i can get it, and i get it going the opposite way to me as well, when i get bad luck, it's usually a chain reaction, 12 player or 2 player lol. Don't think 1v1 has to do with play style at all, it's about luck, and pressure you can put on your opponent with what luck your given.
