Being able to see Energy and Endurance in PvP is a big deal
Ok look, I know countless times it's been said that this isn't a PvP-focused game. But, there is PvP in this game, and in EVERY MMO like this, you can see the enemy players Energy and Endurance bars (or Mana and Action in other games).
Some that don't pvp often may brush this aside, but there are two PvP servers in this game as of current, plus there is dueling in this game on every server. Now take for example PvPing against a healer like a cleric or shaman that uses mana for both damage and healing. It's pretty much blind guessing where you're at in regards to him almost being out of juice and having to run. I'm really baffled that something this basic and simple that is in every other MMO out there is not in this game.
It's not like this is a request for some elaborate PvP system with rewards. This is just something simple that has no reason not to be here.
