“War Mode” in Wow Forever

EDIT: To be crystal clear, this would only be an option on the PvE and RP rulesets. The PvP ruleset would not be able to opt out of PvP, this would be a system that allows PvE and RP players to opt into layers where everyone else is flagged for PvP.

War Mode in retail (at least as I remember it in Battle for Azeroth) is a PvP mode you can turn on and off only in cities. While in War Mode, you are put into shards (like Forever’s layers) only with other players that have war mode on, you get access to PvP specific talents, and get some other special bonuses (extra XP, some extra loot, etc.)

I would love to see something like this brought to Forever, especially now that we know that there won’t be an RP PvP ruleset.

To be clear, I don’t want special PvP talents or bonuses for playing with PvP on while on a non-PvP server! However, I think that having a toggle on the PvE/RP realm that would put you into a PvP specific layer would be awesome.

Effectively, War Mode would allow players on the PvE and RP rulesets to choose between PvP and PvE while in a city. As someone who normally plays PvE (with some interest in RP) but would like to ability to occasionally engage in some fun WPvP events, this would be an awesome option for me. By restricting this choice to cities, you can hopefully avoid players trying to game the system by switching between PvE and PvP layers to try and farm resources, kill rare mobs, etc.

What do you think? Would you like the option to enter PvP specific layers on non-PvP servers? Are there any drawbacks to this system?
