I think there’s value to this idea, because it can be hard to pin down some of those specifics if you’re new to the game or unfamiliar with a specific battleground.
I can relate because there’s still a few BG’s that I’m not very familiar with because they were introduced during times I wasn’t playing much or I had them on the blacklist. Unfortunately, asking a direct question about rules in /bg chat is often not that helpful.
The template they use for defining the responsibilities of DPS/Healers/Tanks in the PvE Adventure Guide would be helpful in giving players an idea of what they should be focusing on in the various BG’s. There’s information on the internet, but as you would expect with fan-made guides for a 15-year-old MMO, much of it is outdated.
The only thing is I don’t want people missing plays with their nose in the Adventure Guide while their objectives get ninjaed. But I’ve seen that anyway with people who don’t use the minimap.
