Just played a pickup with all the new weapons, and here are my reactions
Direct hit- The loss of spam is extremely noticable. When the 2 enemy soldiers went regular launcher at Badlands mid, I could get away with much less, and they were able to pour on the damage, just like old times. However, the DH is still BRUTAL in some situations. Both medics dropped uber once thanks to the fact that they jumped in sight of a soldier. One of our soldiers hit a huge air on Badlands mid from one house to the other, making our entire team laugh at how ridiculous the weapon is.
Scottish Resistance- Didn't see much use, I certainly didn't touch it. When the enemy demo used it he was slower to mid, severely hindering his team on the most important fight of the game. But defending last, he was able to wander quite a bit more while still holding the point locked down.
Targe- Ugh. The enemy demo, on multiple occasions, simply charged our combo and whipped out his sword. He'd then switch to pipes and go for the med. I couldn't touch him 1v1, considering I couldn't do more than 40 damage at a time. I'm really interested in what Valve's thought process in producing this thing was.
Buff Banner- Won us the mid fight on granary a couple times. According to our soldier, the charge was erratic and irregular. He said he could put a rocket on the demo in close range, do 100 damage, and it would go up a little bit, and then hit the med with a long range 50 damage rocket, and it would go up by a third. I kinda like it though, it adds another thing to mentally keep track of, and allows for pushes without uber, resulting in a faster-paced game.
