I have not read all the posts so I do apologize if I ninja’d some ideas.
I agree with the previous posts that PVP is getting more attention than necessary. I would suggest putting it to a vote and let the community decide just how much work should really go into it.
I would like to see the blue diamond plate get rolled back to “anyone can use it to level your character status”. It would be great to put the “easy” back into “EZ”...at least until level 70.
I would also recommend making the UW be tier’d to the zone you are in and the stats match accordingly. For example after the initial starting quest, you would 25 Qvic essences and 1million plat for level 1, maybe 50 CT essences and 1.5 million plat for level 2 and so on.  Until you get flagged for a zone you cannot use the weapon if you progress the weapon beyond the tier you are flagged for. As new zones are introduced the weapon would be increased in stats to match the progression of the zone. Even add an Epic slot at T8 or T9 so you don’t feel like you have wasted time in the Epic quests.
I would also like to see jail be active in the public zones and the aggro increased to 20 mobs, if this is possible.
I think most of us get that not everything will be balanced at all times but the constant messing with items that have been worked for, is very annoying.
