Players like to fight other players and sometimes they like to do it one-on-one, but it is quite awkward to arrange these matches in Lockdown.
Create a sparring dojo similar to the training hall that would allow us to fight against other players with all the cosutme and gear (including shields) we use in Clockworks.
We'd have the health we normally have but no time limit and no game, just a place to spar.
The players could then arrange matches of 1-on-1 or teams or melee.
Make it a guild hall room for us to buy.
You'd be adding new content, something for guild halls, and a major new fun thing to do - all for very little work on your part (I'm assuming).
Add another doorway in the advanced training hall to lead to such a place as well. Sparring Dojo could be an extension of the guild training hall. Both could have different layouts. Maybe the guild versions let you play with the Lockdown shields, but players can default back to their equipped one?
