in beta world class players dont miss 5 1-on-1 in a single match like they miss in full patch
in full patch DM/MC get 6-7 rating almost every game even when they play well, that doesnt happen on beta
on both the board confidence is stull messed up.
in full patch players can't do curled shots, havent seen one for 6 months.
in full patch corners are ridiculous.
in full patch players won't tackle most of the times.
in full patch the interaction between DR/DL with MR/ML/AML/AMR is worst
imo.
i think these ones are enough reasons to go to beta if you can handle the other bugs from beta.
