I feel stupid now, but I completely misread the original post. I thought the experiment involved pitting the different player groups against monsters, but they fought each other... PvP is the height of weird jank in D&D.IMO. It says absolutely nothing about the High Level Martial / Caster divide. PvP is not PvE. To get a true comparison he should have had them run a dungeon.
On a side note, I think everyone is a bit too focused on the initiative. Even losing initiative I suspect the fighters would have won because they can just save against almost anything the casters might want to do multiple times in this encounter. The only difference might be is if the casters have some prep time, even a round might change things.
Also the new indomitable seems reaaaaally good for this kinda thing. Definitely one of the better changes in the new version.
