Self-Destruct is Irrational Component

[dmm]

You guys keep missing my point. I'm not saying that I'm displeased with SDDs from a game-play point of view. I agree with suicide_junkie: it is unlikely that you'd want to board an escort with a mother ship, so it doesn't really matter to the game play. But what bothers me is that a super-powerful SDD doesn't make sense from a story-line point of view. I'll say it again: if SDDs are so powerful, then why wouldn't an empire just make ramming suicide escorts with SDDs that could be detonated just before impact? They could destroy any other ship. For that matter, why not SDD-equipped fighters?

Of course, I don't want this to be allowed in the game, because it would ruin it! So, what I'm asking for is a logical pseudo-scientific story-line explanation for why SDDs don't work this way. And I really feel that no one has even attempted to give one yet. (For instance, suicide_junkie's explanation for why SDDs can be so powerful only reinforces my point, from the story-line point of view.)
