My thoughts on the update:
The Positives:
The 15 minute video is great, easily the best TF2 video Valve has ever done.
Finally some new weapons, it's been far too long. The new weapons seem interesting, especially the BASE Jumper.
Some nice looking cosmetics, I will probably buy the Doctor Who scarf for the Medic.
Some nice bug fixes that have been a long time coming, like the Loch-n-Load fix and misc unequip bug.
The weapons are very easy/cheap to craft (even though they forgot a recipe for the Scout weapon).
I'm very happy they added new taunts and let you equipment multiple taunts at once. I also look forward to seeing what the community comes up with for taunts.
The Negatives:
The update had very little to do with the video, just a couple of weapon reskins and the weapons from the update weren't even in the video. At the very least I was expecting some kind of boss fight with the breadmonster. Maybe for Halloween this year.
No new maps, either community made or Valve made. Since new maps are the thing I look forward to the most in the updates I was pretty disappointed by this, at the very least they could of bought a community map or two and included them. Many modes like Payload or KotH haven't gotten new maps in years and there are some good community ones out there.
I'm not so sure how the nerfs to the Heavy/demoman will work out. I haven't played much since the update launched so I'll have to see but my initial reaction to the nerfs wasn't super positive. I guess we'll see.
The taunts and getting the bread weapons seem somewhat expensive.
I would probably give this update either a 6 or 7 out of 10. It feels like they had the movie finished, and wanted to get an update out before the summer sale so they just threw together what they had ready to go and shipped it.
Weapon changes are good.
The taunts don't work for me (no menu comes up).
Did you equip your taunts? You have to go to the load out and you'll have a button at the bottom of each loadout to equip your taunts.
