I like the idea but if this is supposed to be 20 THROUGH 24 I think you should try to add some other element into it other then purely killing each other mindlessly. I think it should definitely be in a lv 25-30+ zone so we would have to fight pve mobs if they daze or attack us and give us an extra factor to deal with.
Was thinking maybe like a capture the flag kind of thing? Ex. One/two/however many UNFLAGGED people in a certain box like area then the FLAGGED person comes in to try and rescue them. Like a horde druid stealthing through w/e map you choose and getting to the "base" then once there he would need to get the unflagged friend across. If the druid gets caught and killed by an ally person then one the ally person /point at the person the druid tried saving the person would then have to mount up and return to the base. The savee couldn't leave the druids side or run off themrself and can't help in any combat. If a horde comes by and /point at the savee BEFORE the ally gets the chance to them the savee would then be "linke" to that horde and would follow him. Of course you can't /point at an escaped savee until the saver is dead.
This is just a newer/better version of what me and 5 friends of mine did back in bc in ashenvale. We played naked capture the flag while flagged and couldnt mount while a lv 70 person of the opposite faction tried to find us and kill us then send us back to the start. First to get from one side to the other won..
This is just something I thought of
I like the idea of this world event but tbh if it's just random fighting in barrens when it'll be 1 20 per 10 24s I as well as alot of other trials won't be interested.. Add some kind of objective or some kind of twist other then just fighting then gy farming
