Yes they were.
Battletech has a similar to-hit system to your proposal and it's very counter intuitive when you're learning the rules that negative to-hit modifiers are good. Especially since other things have positive modifiers that are good.
This is also why armour saves appear to be backwards - so that when your weapon gives the enemy a negative save modifier that's bad for them.
That's because modifiers in older editions of
40k and Warhammer were intended to be applied to the
dice score, not the target number. i.e, you have a
BS of 4, so the score required to hit is 3+. The target is within short range of your bolter, so you get +1 to hit, but he's behind a hedge in hard cover, so he's at -1 to hit. Most of us would say "OK, then now you need a 4+ to hit", and roll the dice, but the intended mechanism was for you to roll the dice - get a 3, say. Apply the modifiers - 3 + 1 - 2 is 2, which is less than 3 (your target number, from the
BS chart), so you've missed.
Same goes for armour. Power armour gives you a 3+ save (from 2nd edition, anyway). A boltgun has a -1 save mod, so the target makes a save, and rolls a 4. 4 - 1 = 3, so he's saved.
It's mentally much easier to modify the target number, then simply pick out the dice by inspection, but to encode that properly into the rules, the sign of all the modifiers should be reversed.

One of the few games I can think of that actually does this is Dropzone Commander. There, every weapon has an Accuracy value - the number you need to roll on your dice to hit the target. things like the target being in cover or a skimmer make it harder to hit, so they have +1 or +2 Accuracy modifiers, so my tank goes from having an accuracy of 2+ to an Accuracy of 3+ or higher. Battletech is the same, I think.
