My suggestion is to make it so that when someone is subdued, that they are made unhostile to everyone.
The reason for this is Summons. Summons will stand there and continuously attack a subdued player, even when someone is trying to use the player tool to get the summon to attack someone else. The Summoner -could- always open up the Player List and search for the subdued person, unhostiling them, but in the event of a prolonged PvP fight with multiple PC's, this is difficult and dangerous.
Or they could tell their summons to stand their ground.
But I think it's a good suggestion.
You can simply set them to neutral quickly, it doesn't take much more time then stuffing around with the player tool while setting your summons to Stand ground and has been my solution in the past and it has worked fine.
Using the Player Tool is a full round action, even though it's an OOC tool. In PvP, your time is best spent drinking potions, running, charging, attacking, casting spells, etc., rather than spending a whole round to unhostile someone.
Although now that Blackout mode has been fixed, it's another good alternative to summoners.
type /c unhostile nearest when standing nearby the subdued player works effectively, or quickslot it even
You can unhostile people by going to the player list, shortcut should be P and finding the character on the list of players then checking like/dislike, that doesn't cost you any actions only a few seconds of your time which can be used drinking potions, casting spells and so on.
This is no excuse to use Blackout over another mode that is more suitable to the situation. IMO.
Yeah, please no blackout to circumvent. It's a good suggestion... I'm just trying to find all the situations where it would be annoying or problematic.
