Expert proving grounds get insanely harder today?

Is it just me or did the expert proving grounds become insanely hard with ultra aggressive champs today? Recommended rating is 11250 and I got 14500 and I can only manage to beat the easiest leg; whereas before I was able to complete all 3 legs before! Yet there was no increase in rewarded shards. Where the hell am I suppose to get lvl 4 basic catalyst now? Between this and frequent crashes since server crashes on Monday game is becoming less enjoyable

When they moved it the AI became dumb, Miike said it wasn't intended.
All they did was put it back to how it should be
Seatin even did a video where he took his new Immortal Iron Fist into the expert proving grounds. The first thing that happened was that the opponent held his block for an insanely long time. That was normal for the broken version.
