I agree 100% with this post. If you are a PvP player, the whole point of the game is that you build your pokemon yourself. Now the players that will continue playing this way will have a way harder time finding a match. At this point just play showdown lol.
I am not sure on this point, but I seem to get way less BP/MP per match while playing Randoms. A bit strange, but I hope I am just wrong.
Also yes this is not really "new" content, although at least it will calm people for something like 1 month.
Last point, randbats are obviously unbalanced and you can't always expect to have "fair" match-ups, but in my opinion there are way too many eviolite/NFE pokemon and choice item users. Also the leveling seems a bit off, but this is probably gonna be fixed/adjusted with time, so it is not as important.
