On Going Elf Raid Style NGP Raid?

The mechanics of the NGP raid used for the Christmas event are amazing. It's the right mix of having to grind and luck to keep you locked in. I think an ongoing version of this raid would be extremely cool, with a few notes.

1.) It should give mostly EXP rewards instead of items. I think if it gave some sort of tiered exp rewards it could be a lot of fun who want to play without bots.
Example Rewards
1M Exp - Fairly standard round
1 level - Dynamic exp enough to go up 1 level, hits maybe 25 times a day
10 level - Dynamic exp to up 10 levels, maybe hits once a day.

2.) Extremely rare item drops - Mix in rares that would come once every 10000 runs or something

3.) Bonus points for NGP, things like first kill or last kill should give you an extra point for NGP, makes getting there fast and hunting down the last monster worth while. Lots of people lazily get there and wait for others to do the work. Also they sit still when the last hard to find monster is creeping around, so those who hunt those things should be rewarded. Most kill points would also be good.

4.) If pets kill more than 50% of the monsters, no loot screen is provided. You shouldn't be able to do this event mostly with pets.

5.) Different sorts of monsters should be mixed, undead, fire/elect, complete resistances,  so you cant just stack one type of items to be effective.

6.) Leaderboard could be updated to include categories like most runs, damage done, ngp points earned, etc.

7.) no botting or using multiple chars allowed, if this is done punishments.
