The argument that at one point we were in a good place and now we are not and as such should have to suffer is really poor. Why should we have to put up with a poorly designed class when melee only gets stronger as seasons go on. I don't understand how people can logically say "well you were fine two seasons ago so suck it up now." Why is that at all unreasonable that we demand balance throughout all of our time playing?
Actually, its a great argument to show that you really don't care about the game balance as a whole, but just yourself. There are more glaring issues than putting warlocks back up to #2.
