Guild Wars 2

Ayyyy , thanks fam

Played it way before on my friends PC but now decided to get it myself.

1st Question – I bought both expansion in a bundle , do i have to buy the original game too or i can upgrade it from F2P?

2nd Question – What is the player pool size when compared to last year?

3rd Question – Would my Ping be too high if i would play outside EU servers?

Thanks in advance for answers
