I'm just wondering if this is something that has been noted by the devs. Beyond cooldown and damage types, there's no other damage types in StarCraft -
First, some attacks are instant hits, some have an animation of a projectile. Projectile attacks have a slight delay between the unit attack, and the target taking damage. A perfect example is the Goliath, or really any unit with a missile attack - the missiles fire, but must travel to the target. The effects of this should be obvious - the Marine attacks, it does damage, the Goliath or Wraith attacks, they fire missiles that hit the target and do damage.
The other attack type is affected by the unit's "pose" when attacking. For example, the Marine's attack animation is quick - lower a rifle, it takes a split second. For units like the Siege Tank or Devourer, the attack doesn't immediately initiate, the Tank's barrel has to turn around and the Devourer has to rear back its mouth to spit the acid.
I apologize if something like this doesn't make a big difference in competitive play, but it seems like it could. I'm just wondering if this is something that's being noted by the devs.
