i suggest we have lockdown 1v1 making it more fun and easier for people who want to challenge others and test there skills like "whitelancer" has done http://forums.spiralknights.com/en/node/41762 But just on the game sign up screen its self Saying "1 versus 1 match", Leave A comment of your suggestion please!
Might be a good idea to actually challenge a specific individual one on one, like duelling.
On the other hand, there's the problem of 1v1 and game balancing - if that person clearly is a lot better than you then it's not very fun anymore, is it? That and LD is more of a team game (or it's supposed to be), so taking the 'team' out of LD makes it quite silly.
That being said, what if you're challenging strangers? Or do I take it that 1v1 is done via invites only?
