multiplayer antisynergies

I'd like to point out that it is possible to build anti synergy builds in the game.

Right now when 1 player plays cold/freeze, it is an antisynergy build with a heavy stun build due to freeze and stun sharing the stun bar and stun resistance. If 1 player freezes anything first, it's hard to heavy stun anything after that and vice versa.

Is this an intended design, where only certain builds fit with certain other builds?
