Sure, here are several solutions you can implement right now!
1.) Turn on enemy nameplates, click red treasure gob nameplate, or press tab
2.) Press Holy Nova to aoe gob,
3.) Wait two seconds for goblin to move away from initial spawn, then target as normal
4.) Heal anyone, you’re a priest. Literally all you have to do is press Holy Nova ONE time and you’re on its loot table.
There you go, problem solved. Excellent, now that we got that sorted… do you have any other problems, troubles, conundrums, or any other sort of issues, major or minor, that I as a good friend could help you solve?
As a good friend, I feel obligated to be honest with you, you are being overly dramatic about the difficulties you are facing and are blowing this completely out of proportion. Every class has a way to easily deal with this.
DK - Death and Decay
DH - Blade Dance, Immo Aura
Druid - Heal anyone, Starfall, dozens of options here (swipe, thrash)
Evoker - Emerald Blossom, Dream/Fire Breath, many options
Hunter - Dozens of options as well, Barrage for instance
Mage - multiple AOE options here
Monk - spinning crane kick, heal anyone
Paladin - use the target dummies to drop consecrates, Divine Storm, heal anyone
Priest - Holy Nova
Rogue - several options, Shuriken Storm/Fan of Blades for an example
Shaman - multiple options, but chain lightning on the target dummies till you target the gob, heal literally anyone
Warlock - dozens of options
Warrior - spam Whirlwind
Its not hard, even with toys up, there is no reason to pretend it is.
And then the gob spawns and it moves off the toys. This isn’t an issue.
