I believe all mLife properties follow the specialty slot rule. It's usually only applied on the progressive and themed slot machines. mLife doesn't do point multipliers on comp points, they do the tier bonus (Pearl@10%, Gold@20%, Plat@30%, NOIR@40%).

I know Cosmo stopped status matching mid-last year. If you have a good play history, visit the Host Desk @ the HL room and see if they can offer you something. I doubt they will give you a good offer unless they verify you as a strong player at another property.
