Discussion Combining 2 Annihilation Classes

In an alternate universe, Annihilation on shotbow allowed players to combine 2 classes to use at the same time, receiving both benefits and disadvantages of those classes.

Which combination of classes would be the most overpowered and why? I am looking forward to your answers!

Scout and Pyro (Removing the main debuff from scout, fire)

Thor and Bloodmage (Lowering enemy health by 2 hearts. Then another 2 hearts of damage by the thor hammer, plus having resistance)

Tinkerer and Bard (the absolute support class)

Sniper and Robinhood (Making the sniper bow better, unbreakable and having infinity on it)

Transporter and Handyman (Ultimate nexus life gatherer)

Enchanter and Teleporter (Handy for gathering xp and enchanting fast, while staying safe)

Thor and Defender (good luck killing a guy with nonstop regen and restistance)

Scout and Acrobat (Yea. Give up catching this guy)

Bloodmage and Succubus.

What about berserker and tinkerer? Free hearts on absorption pads!

I'm not sure which of these combinations would be the favourite though , maybe the scout and acro?

Assassin + Handy would be OP
