--d Building take less damage from player weapons.

Question: What about building-only weapons (rock catapult and Burning projectiles)? I've noticed that these weapons do massive damage against buildings. Do they have a damage-type advantage against buildings?

Buildings take full damage. There are just some abilities which are only dealing half of their damage to buildings. Player weapons are not affected by that, just like the two building-only-weapons. They have a 50% bonus damage, but only compared to the price you pay for them, they are still dealing exactly the damage which is stated in the tooltip. Maybe it does look like they are dealing more, because their damage per shot is quite high.

Its true that everything is a bit confusing, but it has been like this, since the very beginning of BT. The only change is, that there are creeps now which have a magical attack type and an advantage against tanks.
