My thoughts:
The new weapon slots are epic. IE mac 10 and chainsaw. Im not sure why people are complaining about veteran players being confused. Change is part of life, and this change is for the extreme better.
If you have chainsaw you don't have another heavy weapon. It makes switching weapons much more accurate because you don't have to sift through things to get to what you want. Now that pipe bombs are so expensive, instead of using last slots on zerker for bombs, I now sometimes buy a machete for fun. Now when i switch to knife from chainsaw to run faster, i have a stronger knife to chop for fun if I need. Before, this would be harder to do for fun, because I would have to hit the same button multiple times to switch items raising the chance of miss-pressing and being forced to go through selection again.
I almost died, and did die a few times solely to the new weapon slots, but why *****, you will get used to it soon enough.
I agree with pipe bomb price hike but I have some thoughts on it. It is always super lame to have a demo dude higher level then everyone with more money running around spamming pipes... but they are needed, especially for a demo dude and a law. What if the demo pipe bombs price rose with however many you had like a multiplier? So the more you carry, the more the next one will cost type thing, and use this in a way to alter the cost of the pbs for each class.
thats all for now
