So I was thinking about future trials and thought - hey, what if there was a trial that in the middle became a battleground and then merged back into a trial? As in, the midpoint boss of the trial would be each other?
I'm thinking out loud here, but a site like Labyrinthian might be perfect for this. The first part of the trial would be normal - the 12 man group advances through the trial to the midpoint, an arena. There, you either enter as four-man teams, or it's every man for himself until four remain. Those four advance directly to the the next-to-last boss and hold it it off or kill it while the other eight are tossed into the labyrinth in various locations (four on one side, four on the other) and must battle their way through the maze to get to that boss battle.
If the four-man winning squad can kill the next-to-last boss before the other 8 get there, they get a very special drop. (The left and right squads will have to enter together.) If one of the losing four-man squads makes it to the pentultimate arena before that boss drops, the boss gets an Tier 2 add. If the two squads can kill boss and add before the third gets there, they get a special drop (but not as nice as the solo squad drop). If the third squad gets there before the boss and add is killed, a second add drops. Then at the end, they all get the normal boss drop, no special drop. And any group that doesn't get to the pentultimate arena before the boss dies gets NOTHING. You Lose. Good DAY, Sir. Of course in this case, maybe the "special drop" is a special buff like doubling your mundus stone buff.
Or perhaps there are three Tier 2 bosses in the pentultimate arena. Each would give a normal boss drop. One is released for each squad that enters the arena. So the winning squad from the battleground stage will get three drops, the first group to enter gets two (or three if the winning squad can't dispatch their boss). And the last group to enter the arena risks only getting one drop from the arena.
And then all 12 advance through the remainder of the trial to the final boss.
Does this sound like something you'd like to try? A PvE trial with a distinct PvP component? There are probably a few permutations of this idea that could be done.
Been there, got the Molag Bal polymorph.
