An interesting idea. I would still use the usual way, to TP foe into the traps rather than bringing the traps to the enemy.
But certainly is useful if you need to take your traps from 1 spawn to another.
TP Foe can miss and you only TP one of enemy into traps. My thoughts with Team teleport is a big boom of all traps on all foes with no miss.
Someone feel free to correct me if I'm wrong, but I think that as drops like Trip Mines cannot be targetted then they cannot be Team Teleported either. 
Im not sure has anyone tried this? My understanding of team teleport is that pets, team, and everything freindly gets teleported to desired location (not even a prompt). You target the location for your team to travel to, and anything next to you gets whisked along like it or not.
I dont know about trip mines (never played that far) but I think many of other traps corruptor secondaries can be targetted in any case???
So I would IMAGINE all your traps get whisked along with you to happily instantly explode simultanously around entire mob?
What are clickable pets (and therefore appear in your pet window) -
Acid Mortar
Force Field Generator
Seeker Drones
What aren't clickable pets (and therefore don't appear in your pet window) -
Caltrops
Triage Beacon (not sure)
Poison Trap (not sure)
Trip Mine
Time Bomb
If it isn't in you pet window, you can't use Team TP on it.
poison trap isnt clickable for my MM at least.
Wish i had tried this in RV event 
Has anyone actually tried this tactic? or have a traps corruptor they could copy onto training to freespec try this method?
Triage Beacon isn't clickable either.
Hey Ho Chaps...
Little thought I had...
Traps corruptor lays down his arsenal of traps
Team teleports himself and all his traps into mob...
Would this work?
