Here's some reasons there should be a complete wipe of guardians and progress when the beta ends.
First, Everyone should start on equal terms.
I know people who skipped Beta but are going to play the full release alot. I want to play with them, cuz it's fun you know .
I'm pretty sure a select percentage of PvE-oriented people want to go all in to get world firsts on raids legendary difficulty.
I know it's just a few hours headstart, but that could make all the difference..
Also, who knows what's been changed in the full version from what we're playing right now? Beta builds are usually a few month old and pretty much could've been changed in the full version.
As for the arguements that includes "We should get something for playing the beta", we do. We'll get something no one else will get.
"But I spent so much time grinding for this and that, It sucks if I dont get to keep it" really? It's not like Bungie forced you to play with a gun to your head, And I bet you'd play just as much even if you knew you would'nt get to keep anything.
"But I've payed 100 bucks for this"
No, you didn't. You payed 100 bucks for the full game, the guaranteed beta-invite was just a pre-order bonus.
