Some people are not going to tag repair or put any points into it for roleplaying reasons.
Their choice. If they're worthy of the title "Roleplayer" then they're familiar with the concept of actions having consequences that must be dealt with.
While I would love to see them be utterly screwed for doing so, it's not fair that they should be unable to make full use of any piece of equipment so a repairman with peak skill should exist.
Show me someone that defines "fair" as "I can screw my skills up thoroughly and still be uber 'cause the game holds my widdle hand for me and coddles my mistakes" and I'll show you one sorry excuse for a roleplayer.
Maybe for such ninnies we should also do away with death and having to reload a save...after all, "
it's not faaaaaaaair" to make people feel like they've failed. Let'em reappear in town with a big "Oh, you made a whoopsie!" sign on the screen.
