Just want to add that I don't even need to pay to play unlimited PvP. Warhammer Online (which I think had some of the best pvp combat) now has the unlimited free trial meaning you can rank up a toon to ten and pvp (and pve) as much as you like in the first zone for nothing. I bought and played the game at release and it was fun but there just wasn't enough to it. However I still can play that game and get a more rewarding/less restricting pvp experience with a trial account. Matter of fact I still do that when I need a good PvP fix.
What I'm saying is if they want my money here they are going about it the wrong way. I'm not paying (likely more then a sub price) just to PvP. More specifically to die in PvP. That just adds unneeded frustration.
Also if all they can give us is six slots for $20 then I'm going to /sigh over that too. I was all set to deck out my three characters with big bags/banks, but I can only imagine what the 36 slot would cost if these prices are accurate.
Hate to seem like I'm whining, I'm not trying to sound cheap. I just look at things as a critical consumer, and there are games out there right now which can satisfy my wants for more reasonable prices. I really like this game and see enormous potential in it, just seems like the Dev's saw that same potential, got full of their own hype and greed took over.
