Uhm...do any of you realise that this is a preview and not the PATCH NOTES.
They said a lot of big things were coming for PvP in 2.4, not that it would be only pvp or mostly pvp. I don't remember them saying that.
They now gave us one example of what is coming. What part of this preview now makes you think that this is it? Honestly they said they were going to do some major things in 2.4 for pvp...they didn't say it would be pvp only or centric as far as I remember and again...these are not the patch notes. Ask questions for more information but these reactions about pvp only getting these extra warzones might be a bit premature.
Because Bioware are good at setting our expectations high by announcing things in advance.
