ignoring that it would take away from PLD's identity of course things would be different.
As long as Tank A has the same damage and can tank as fine as B and C while also bringing something on top of that, you take tank A.
Though people will always check what's best in which situation. If you remove the utility ppl will compare damage. if the damage is equal, ppl will compare survivability. and if this is equal as well, maybe then ppl will choose what they actually like. but then you have others that will likely complain about homogenization...
