This is a pretty boring suggestion and therefore one that could probably be easily implemented but that's what this subsection is for.

1. Free-form PvP
If Lockdown and Blast Network are the Gates, this would be the Advanced Training Hall. It'd basically be freeform PvP with no catches like classes or special bombs to get in the way, taking place on Lockdown maps with no actual objective other than 'fight each other for fun.' There would probably be no time limit on the maps, allowing players to come and go out of the fights as they please - again, much like the Advanced Training Hall. If other forms of PvP were implemented in the future, their maps could be added to the selection as well if they were fitting. There wouldn't be any rewards for fighting here other than fun, but no entrance fee would be present either. Tier rules from Lockdown would apply, but that'd be the only restriction in place.

2. Dueling
Once again, another fairly simple request. Two players could agree to 'duel' one another and pay a small entrance fee, at which point they'd be put into a slightly modified Lockdown map and would fight each other one-on-one, using no Lockdown class shields or Blast Network bombs. The fight would go on for a period of time (say four minutes for the sake of convenience for this example), and the game would keep tally of how many times each player has died in comparison to the other, and at the end of the match the kills would be tallied and whoever had more would win a slightly more modest sum than usually comes with PvP. Healing via pads wouldn't do anything, and camping would be impossible because the spawn area would be protected from gunshots but would also take one of many ways to end up "encouraging" the player out (hard-hitting spikes triggering after a set amount of time after spawn, fire traps doing the same thing, literally slowly moving the player out over time...) It would also be impossible to switch equipment sets mid-match, mostly to prevent players from developing meta-sets that would counter what their previous sets' counter would be. Accepting duel requests could be limited to accepting from all players, accepting from friends only, or accepting none. Naturally, this would be voluntary from both sides.

Possible issues with implementing these: server strain (especially from the former) and not having a huge amount of point to being implemented aside from the sheer fun factor involved.

Thoughts?
