Pve events, decent ones at least, would need more attention & planning. Pvp events are preset guidelines where players are the challenge theirselves so obviously its easier to implement I think they're still testing & creating assets for a decent pve event u like queens wrath. U can just do dailies at lvl 30 or story at max lvl for more "pve events" like the last 1. I'd rather wait & allow bungie to create a great event than rehashed story missions again
