I will give a suggestion that may be exceedingly unpopular among pvmp players. But I am trying to focus on what could encourage the new players that we seem to have a good number of to jump in to pvmp.
PvMP has, of course, a huge barrier to entry. People on either side that have been playing for many years have an enormous advantage in ranks and gear and skill. Newcomers are fairly well guaranteed to lose any one versus one fight against an experienced player and to contribute very little in mass melees. Some people do not mind this and are willing to endure months of defeats to "pay their dues" and catch up to the point where they go from almost totally useless to not very productive. But many others don't see the point - not in a game where a new and poorly geared player can do quite well in pve. How can we reduce the barrier to entry? Player skill is not something we can fiddle with - a brand new character with the crappiest of starter gear will still have an edge if run by one of the better pvmp players. But can we neutralize ranks and gear as factors? Not permanently, of course, but temporarily just to get new people involved on a "fresh start" or "fair chance" basis.
Option 1 - probably not feasible because so many existing players will absolutely hate it. A fresh start pvmp zone. Perhaps a clone of the Moors. No existing ranks or gear allowed. Perhaps a Treebeard type of slow progress to keep it that way for a while. Maybe with rank caps going gradually up - call it a progression pvmp zone.
Option 2 - similar concept but less likely to cannibalize the current activities in the Moors. Limited availability rather than (or in addition to) progression features. Maybe available once a week. Maybe available like festival zones are - once a month the Moors "festival" becomes active for a week.
This is a great idea. Maybe two Moors: Intro Moors for those who are just starting out and a veteran Moors area. Ability to enter the intro Moors area could be restricted to low ranks and less than level cap players. The NPCs in the intro area would be scaled down appropriate to the players. SSG could even make a bit of money selling tortoise stones to prevent people from ranking out of the intro area for those that want to PVP in the lower level areas. It might even slow down the farm groups who camp out for new players on both sides.
