Huh?
Pretty much most of the BG forum regulars (…and especially the premader posters) use PvP consumables extensively and basically every day
wPvP is mostly dead outside of the start of seasons or people doing a one-time weekly quest, no reason why consumables should be made “exclusive” to it when the content itself (wPvP) is dead most of the time - seems like a waste of these fun/cheesey items if almost no one uses them due to being made “wPvP only” (mostly dead content)
On the other hand, casual/random BGs are true evergreen content in that they stay fairly active even during content droughts (since there’s not much going on in the rest of the game). Spicing things up with having some more PvP consumables sprinkled into the casual sandbox of random BGs is fine, the changes made here are good
