I don't really get this. Why is it so easy to believe in the (utterly unrealistic) inescapable explosion which one can never escape; but so hard to believe in the (far more realistic, I think) fighter who always wears down opponents in 6 seconds of clashing with them?
Because, firstly, the ability is always on. Or did you miss the bit about "eyes gouged out?" And because, secondly, it makes it impossible for the fighter to have an unproductive round in melee, making, imo, the game less fun by reducing tension (even if only by a modest amount).
That's the point. The player who spends PC build resources on this ability is purchasing this capability for his/her PC.
You may or may not like it, but I can't see how there is any denying that this is a real choice, with real playstyle implications.
I don't know that I ever tried to argue it was not a choice to include this power in the game or for a player to include this ability in their character's abilities. I just don't think its a good choice to include it in the game, because it does inherently have playstyle implications. It is the sort of ability that reduces playstyle choices rather than broadens them.
Though frankly, I don't see why you can't just ignore it. I mean, suppose the rules were published without this ability, and you went about using them in a truly satisfactory manner. How does it change all the other rules, and their truly satisfactory nature, to also include this as an optional ability?
What a great idea! Next time the whole fighter vs. wizards debate comes around, I am just going to tell people that "Pemerton doesn't see why you can't just ignore it. Suppose the rules were published without this spell, and you went about using them in a truly satisfactory manner. How does it change all the other spells, and their truly satisfactory nature, to also include this as an optional spell?"
I am sure that will cut the whole debate short.
Or maybe not. Perhaps people would respond that, in their opinion, it showed poor design work on the part of the designers and that they don't like buying a game and then having to promptly ignore bits of it. Or they will say that if its in the rulebook, then players should be able to use it, because to do otherwise is unacceptable DM Force, and who wants to play with a DM that just tells players what they can or cannot do, when the rules as written say otherwise? Afterall, we want to play DnD, not Calvinball, or Pemertonball.

Seriously, if the time to advocate for this sort of inclusion/exclusion in the core game and its sensibilities is not now, then when is it? After the game is published, if the designers have chosen to include this sort of ability as a standard character choice, it is then that we can give it, and/or the game, a pass.
