A little bit confused

[FireHunter]

I bought a GOLD+VIP subscription last year with unlimited classic access
So nothing changed for me ...
But now a friend of me wants to buy Graal too
And he ONLY wants a Lifetime Classic subscription

Now I get confused with Observer Mode and a lot more things

So a little short Question:
"Can a new guy buy Lifetime Classic ?!
And if a new guy buys a higher subscription like Playerworlds does he still have Lifetime Classic after it got expired ?!"
