Never assume that the person whom you are talking to is ignorant of these. Yes, many do not read the DMG, but for those that do, some changes that seems inconspicuous are actually a big change in the philosophy of the 5ed design.
Remember that 5ed was built with the players input and went for what the majority of that time wanted. Not everything that I or we wanted needed up in the 5ed. But it was mostly what we all wanted it to be. Now they are changing their stances and it is seen as a betrayal by many. If they want to make a new edition, let them go ahead but leave the premises of 5ed alone.
And guess what? I would buy 6ed in a heart beat. I would buy it with the monster stat block they are using now. I was a big fan of 4ed. And I recognize they way they are going in how they are doing things, but this is not the 5ed they had offered and promised. We got what we got and we were happy with it. If WotC really want a 4ed revised into 6ed,so be it. But they should go ahead and do it. Not that sneaking around like what they are doing right now.
