Guild Wars 2

Current problem:
Upon the game’s release, arena net promised 3 roles all players must follow for a successful party. Control, Support, DPS.
Currently, everyone focuses on DPS, as with proper gameplay, for better or worse they can avoid all the bosses attacks. There is some support here an there, but nothing special.
The control role is missing entirely! And the reason for that is because you can’t stun or launch, and generally “control” a boss.

Solution:
Obliviously, simply making the boss stunable and/or launchable won’t do the trick, as players will simply stun-lock the boss to death.
The trick is to create a new type of stun and launch effects that instead of making the boss fall back to it’s face, it should simply push it a single step back (and preferably with some new “being pushed” animation when attempting to launch), and instead of getting stunned normally he’ll get stunned only for 1/3 of the normal time.
That way, the stun moves of the entire party will be effective, each giving the entire party one second to breath, effectively interrupting possible death skills by the boss, and at the same time with co-ordinated launchs the party could move the boss without using agro tricks or sending the enemy to far out of the melee player reach.
If the party still finds a way to abuse their reduced stuns/launch, and find a way to take turns and stunlock the boss way to much despite the reduced effect, or the phase of the battle requires the boss to cast a scripted skill, then the boss will temporary get the usual “getting annoyed” boon (unshakeable) as a penalty.

Edit:
Fixed some confusion about stunning and launching.
For me they where pretty much the same thing since they have pretty much the same result of incapacitating the enemy for a short while.

I’m not sure you know what a stun is… stuns are completely stationary (in fact stun blocks movement, this is the difference between a stun and a daze) and most of them are already a second. Also pushing a boss backwards through whoever was smart enough to be BEHIND it means your squishy melee is now out of position and since they have the boss targeted the game won’t let them walk straight through it so they probably just had to waste a dodge to get back to the other side of it to avoid any cleaving attacks.

I use an Engineer, and all my stuns are tossing the enemies around.
I rarely experience a stationary stun.

The point is that to make the “control” role relevant, stuffs like those should work on bosses.

Again, stuns do not move enemies, launch and knockback do. Nobody walks into an ele stun field and flies away.

You do if there is a wall of reflective force in it.

I made some changes to the OP.
It should be more clear now!
