Board Game Arena

does anyone else find the arena scoring is simply not fair? the difference between certain games against opponents with different points is really not proportional. Other games that I play in arena mode are very different. It really seems stacked against the weaker players. And to keep playing against the same players - i've played 3 in a row against the same person once, and there is another player, who is at a 600+ level, who I have come up against incredibly regularly - I get that sometimes there is only a few players on at a certain time, but perhaps there ought to be some kind of limit that would prevent you playing against those who are more than 100pts above you on a regular basis.
I've definitely improved my game through arena, but my sense of justice is not happy with the current scoring system. I really hope that it changes in the next arena.
