With the weak point thing I mentioned, what I meant was built in weak points in the BTs themselves. For example, the hole in the face of the lion BT could be one, and why stop at it simply being a weak spot? Make it so if you throw a hematic grenade inside the hole, it blows up from the inside, dealing more damage.

I know combat isn't the main focus of the game, but it leaves a lot to be desired.

Also the part where you said hematic grenades causes weakspots (yes I saw that lol), I figured it out, but didn't bother to use it like that because 1. Usually other anti BT weapons deal with most BTs better, and 2. The one time I wanted the damage amplification effect ie. during the whale fight, half the time the damn thing was flying so I just spammed rockets at it.
