Better Rewards for long term Nitro members please.

So, I'm currently a Nitro member; but, quite frankly I hardly see any real benefits to this subscription. Every time I get a gift redemption (I get so happy only to be disappointed soon after when) it says I'm not allowed to use it because I need to be a new user for it or that my region (Puerto Rico / Caribbean/ USA) is not supported. (Example: Nitro, YouTube, Xbox, etc.) I find it unfair! I'm also paying for Nitro, why can't I also get the benefit like everyone else? Sure the recent customization options are nice, but right now it all feels a bit lacking. I would like to see more exciting or exclusive things; otherwise, there might come a point in which I simply stop my subscription. I can't be the only one feeling this way. Who else is annoyed at this?
