Hello champions, good to see you.
So, let's be honest here: Best is really subjective, I know. People love to point at me because of my love for this game, and it's totally fair, but let's take a moment to discuss the F2P model of GW2:
You get the full leveling experience
You can create every profession, except Revenant (a fair trade, IMO, as they're all cool.)
You can create up to two characters (Not that many, but hey, I have the full game and I only play with Lotus)
You can enjoy PvP in it's entirety.
You can play WvW in it's entirety.
You can basically play one of the best MMO/game ever made in it's basic form for free, which is a very cool thing to do. Other games offer a lot of restrictions in the overall experience, and I think that GW2 is super fair with that, which helped the game a lot.
What is your opinion on this?
