I got beta. I was in beta since beta 2. Still got merc edition. I've got my freeagle, SOL and Founder's World permit.
That was standard beta and you got the founders worlds and sol permits because of a bug. There was only one mercenary edition and that was the pre order of the game that DIDN'T include any beta access.
Some people are confused and FD are playing on that to pull a fast on us as they offered several tiers of pre release access AND pre order and LTP.
How much did you pay?
Standard beta cost 75$ USD
Premium cost price of standard 75$ usd plus price of stand alone lifetime pass 50$usd.
The pricing at the time was pretty clear that the difference between premium and standard was LTP and so they offered it in a package known as premium or you could buy it in pieces(75$ for standard and later on you could buy LTP for 50$) if 125$ was too much in one go for you.
It's pretty clear to me beta access went with both premium or standard, LTP is just a lifetime pass to access to all xpacks and has nothing to do with beta access or not.
