The insane combo we are doing, is actually just a small upgrade from what most arena teams are already using. A LOT of people already use
Reaping Flames, and quite a bunch use the
Remote Guidance Device trinket.
The different thing we are doing, is "manipulating" the spawn of the
Remote Guidance Device wheel. A weakness it normally has is that it can be soaked and bug up during its travel time. It gives the enemy team time to react to it.
However if you spawn the wheel at a wall, it won't be bugging out
It will instead spawn right on top of you. Meaning if an enemy is in your melee range it blows up instantly.
Combining this with stacking Versatility, as well as your whole team using 3
Remote Guidance Device at the same time, and
Reaping Flames for your DPS. (
Anima of Life for Tanks, or
Concentrated Flame if you play Healer). You can easily global anyone except the tankiest enemies. Such as Arms Warrior in
Defensive Stance... Unless you are lucky with crits.
Having a Death Knight is also really important for the Death Grip, so you can bring the enemy to your wall.
You don't actually have to do it in the beginning of the Arena, if you just coordinate with your team any pillar or wall will do. Just make sure you face away from the pillar or wall so that the wheel spawns on top of you for instant damage.
