Should the only gear be used for PvP be PvE gear just like in Vanilla?
1) You're more motivated and excited to do dungeon and raid. You know that your gear is not bound to instances only and be useless outside. If PvE gear is used for PVP gear, you feel more prestige with it, like it's worth more. You can look forward to showing it off too people in places like Cities, Battleground, and World PvP. If there are PVP gear, your PvE gear is just like W/E u can only use them in instances.
2) People who cannot get purple from raid bosses can still get high quality gear, just not the best, like Lightforge armor or it's casual upgrade Soulforge... if you're not a raider. This way, you'll be in awe when you see people who actually have the higher gear. Like for an example, if you're in blue Lightforge but see someone with Glaive of Azzinoth, you don't have it but it feels great to see it. You can have like Lightforge/Soulforge quality gear and be like a "High Lieutenant"... but you are also more motivated to get into raid and get the bigger gear. PvP gear makes it boring.
Don't you guys think PVP gear should be abolish and the only thing left to use for PVP is PvE gear? I think they should go forward with this, not back. This will make WoW more exciting IMO. I want to show off my gear and let it have more use then outside instances like raid and dungeon. I like showing off.
