okay okay, I understand that ANET wants PvE and sPvP separated, but I think there could be couple of ways do this:
For example, since this game doesn’t have rested xp, there could be rested xp for gaining glory in spvp – for example you gain one glory rank and now you will get double xp for one level in pve (or more levels, since glory is so much slower to get than xp). This would need to be probably bound to character (so only glory gained by that character would yield him this xp bonus).
Second thing seems even simpler to me – just let me buy golds for glory. You can trade them for gems and buy xp boosters or you can buy better armor.
