About this topic: ugh, another person ‘discovering America through one’s window’, i.e. the issue of bots, discussed a lot on these forums.
In short, the proper solution to that would be to address the issue of bots, not to shut down the mode — obviously enough (although what is obvious for a person playing such decks? Not much in this world, probably…).
I don’t recall whether I’ve reported it all and for which months in particular, but yes, sometimes the streaks between D5 and low Legend have been particularly riddled with especially bad bots with basic decks.
Oh, yeah, another one of those…
I find your analysis rather superficial, but it’s been discussed many times already, don’t feel like repeating myself, sorry…
