Not only can u get exp from this, but also prizes.
The map in which we would use is is much larger than a normal pvp map., more or less the size of a guild hall, or an explorable area, such as talus chute for example.Also, maybe like 30 players or so can fit in 1 map, with them of course being randomly placed and assigned per map, to prevent teaming.
This does not mean teaming is discouraged though, so be aware of who you may trust as an ally or a friend.
I was thinking of several possibilities of scoring. One is that, for example a match lasts 20 minutes and whoever gets the most kills wins.Or, it is simply a "last man or woman standing" game, where the last person gets a suprise chest that leaves a special surpise inside, an item, maybe a little money, or simply just an explosion that instantly kills you.

Also, in terms of dying, once u die u get dp obviously, and u get teleported back to the place where u started the map,or a random place. There are no special rezzing places, because ppl can just hang out there and wait for respawning ppl and get easy kills that way.
For every kill that u get, either u can get a small amount of faction points or maybe some spare change, like 5 coins or something. A small reimbursement, but i think it would be much more fun teqhnique of making money than farming, even though ur profits are so small.
There would also be new titles, such as unstopabble monster(for the crazy lunatic who goes on killing sprees), King of the hill( for the person with like 1000 or so times left standing last), or other things as well. Also, these arenas i guess would be designated as ONLY LVL 20 ARENA, so that weaker players lvl wise cant be taken advantage of. Every1 must be the same lvl, so that it is more fair.
Ok, this is just a rough sketch of the idea, please feel free to post ur comments and potentiel improvements and if u support it. This is not a petition btw, at least not yet. I want to develop the idea more first.
