I think they will not pause the draws because of PNPs. PNP draws are sacred to them.
As for the CRS score, I think its totally worthless as a measurement. Why ? Let me name you a few :
1. Who came with the idea that a bachelor or Master should be valued the same for every country and university in terms of points ? I would think one from Germany, France or UK are somehow equal, if we compare the best universities one on one, but one from Albania the same as one from UK, what the F*ck ?
2. Sibling points. Complete worthless and discriminating, literally. Plus, favors chain migration, which no country should seek it for a million reasons.
3. Canadian work experience points. As worthless as they can potentially be. One working as an engineer and one working as a burger flipper, apparently are the same in the eyes of Economic Immigrantion. One needs a bachelor, a master, some years of experience to get there and the other just hands and legs to do the job, but hey, they are working in Canada, so 30 - 50 points gratis for them.
4. Canadian education points. If you are graduating from a reputable university, like UT for example, you deserve not 50 but 80 points for that. But, if you are graduating from a university migration mill as Lambda College et al, they cannot compare to the top universities in my country, let alone with the ones in Canada. 50 worthless points for a bachelor.
So, bottom line, I think they want just numbers for the time being and won't stop those draws.
