It wouldn't be anything complicated. Turning the shooting range into a small, simple mini-game may give training halls more purpose, act as incentive for guilds to use them, and foster fun competition amongst guild mates.

All it would do is keep a record for speed and accuracy. The targets would probably have to have a slight increase in difficulty (but the training hall is split by tiers so maybe it can increase depending on which level you're on) and a scoreboard beside it would have the name of the guild member with the highest speed and the best accuracy.

Guilds could also take advantage of it if they wanted, and give awards/rewards/prizes at the end of each week or month to the top gunner.
