Hey,
I don't mind that at the start of new tier/season you have to "grind" 7800 points before you can buy those weapons (we don't want to force pve-players to play pvp, do we?), but they could really consider removing that at some point.
With the current system it's really pain in the ass start new character for arenas mid-season. You have to play arena ~4-7 weeks before you can get your weapons (depending on what rating you are capable of playing.) It doesn't really help that almost everyone who you face will have already those better weapons.
Maybe i'm after "welfare-epics" (yeah like raiding isn't easy as well), but I would really like run multiple characters in arena and get sum weapons for them. If you have to skip one or two weeks, it can take you over 2 months to get your weapons :/
