Just a quick question: What does the Terran "Burst Lasers" upgrade do? It's found as a normal (not unused) upgrade in Scmdraft, but I do not remember seeing it in-game anywhere. It shares the name with the wraith's ground attack, but it does not appear to do anything on first sight.
None.

Quoth the raven, "Swag galore."
In very early versions of StarCraft, you needed to research it for Wraiths to have their ground attack. It doesn't do anything now because they don't need it any more.
It would be funny if we could set it to disabled and wraiths couldn't have ground attack.
None.
Or you couldmake ground attack negligible. ie. 0
None.
If everything else does, say 50 damage, and units have over 200 hp, I'd say .5 damage is negligible.
None.

So if you have over 100 wraiths it would be negligible? No.
Anyway, there are no "what ifs". The upgrade is completely unused.
