I honestly think the best way to revive Pvp is to make a new centralized area in a major hub. Whitegate makes the most sense. Do away with the "pit" area, and make it a coliseum. A place where you can PvP or just go to watch/bet on the outcome of 1v1, 3v3, and 6 on 6 matches. The current format of ballista with the annoying wait times, and capped blah blah blah is aggravating. Make this uncapped with the afore mentioned 3 sec stun on gear swaps. Brenner doesn't offer the option for random ppl to come watch because it is instanced. The coliseum plan allows for the best option imo.

Rewards of town gear models, costumes, furnishings etc. only acquired thru PvP would be perfect. The game needs this addition. What ever resources devoted to the development of this concept would continue to pay dividends far into the future. Not only with the same content being reused again, and again gladly, but it would go a long way toward retention of accounts. When players get burnt on the grind of gearing out jobs, and end game this would always be there as an alternative. Duking it out in a public setting with bragging rights on the line just never gets old
