Should there be a class restriction in PVP?

[intrepd]

So there is no class restriction in PVP that's why most PVP players complain about "Tank stack" or "Mage stack", i would like to take feedbacks about class restriction, is it a must to have in PVP to solve it or not. My opinion is yes as for 2 per class a team at least it will be stopping Tank stack and Mage stack.
As for now whenever i go TDM i usually see 3 tanks per team if not 4.
Would like feedbacks about this topic and also would like a dev/mod to check this.

-This is going to help by making all classes participate.
-No more stacking classes.
-Both teams will almost have the same setup
1 tank 2 mages 2 rogues
2 tanks 2 mages 1 rogue
2 tanks 2 rogues 1 mage
Will be the avaliable setups
-Will limit the ganging by a bit, most gangs nowaday are tanks and you got to prepare your team before clash or join a random team.
