In all my years of playing paper magic I have never encountered mana issues as much as on arena. Every game you either flood out or can’t draw a single source of a color. Running a 3 color deck in draft with the mana split of 8 sources 8 sources and 7 sources and managing to somehow not draw a single color is absurd. Once in a while sure it happens. But in a single draft to have mana problems on say 4 out of a possible 9 games is insane. The “algorithm” has an issue that seriously needs addressed.
Along with that. Playing in any format the amount of times it feels like you lose the coin toss and play second is crazy. Someone needs to track how many times they go second and see if it truly is 50/50 because it honestly feels like a 25/75 split and I’m on the losing end of that coin toss a lot. When playing formats where aggro is king it makes the game way less enjoyable when you immediately start on the back foot. Then a diety help you if you happen to run into the very very common mana issues along with playing second.
