Tbh im glad that you noticed that they lost from winnable score to kru, because this is literally their problem soo far
I knew some impressions from players who played vs FNC and some opinion from them is that they are very very readable with a matter of time. Even Derke in interview to Thorin said that they are very hard relying on their scripts like robots
They can have lead score but they kinda choke all times because teams just adapt to their playstyle and scripts even during the map. Some maps vs Sen in iceland were with lead, in stage 3 VCT EU same(vs G2 and etc), vs C9 they were like 11-7 and then made it to OT lul and KRU as you noticed.
The reason why they were successful at champions i think its because they had element of surprise (their fracture for example) noone really knew how they gonna play because they didnt played vs any T1 team officials on a serious mode for a halfyear, but still it was very hard for them even with defaults that they never showed before, isnt it?
I think this is why they force to make roster changes, because its mb for a time but it makes them hard to read until everyone will adapt again
Maybe im wrong this is just how i see it
