This update sucks!
I dunno, while I do have mixed opinions about it, the items themselves are not so bad.
The only item that I really do think is significantly unbalanced is the Pyro's Power Jack.
It deals 25% more damage
It restores 75 HP on a kill
It doesn't deal critical hits
This is clearly an upgrade from the axe, loss of random crits is not a significant loss to warrant these advantages. The axetinguisher doesn't do much damage to enemies not on fire, the homewrecker isn't too useful against anything but engineer buildings and removing sappers - those are both major disadvantages that make up for the specific benefits.
For a very long time the Medic's Blutsuager was clearly an upgrade for the same reason.
With the old Blutsauger, you traded random crits for the ability to steal health from an enemy! Somebody (not me) who is good with aiming that thing could take on most classes because they kept gaining health.
And losing random crits? a minimal defect for such a power.
Of course now you constantly gain more health if you use the regular Syringe Gun - and for a Medic who doesn't do much shooting like me it's preferable to the Blutsauger.
Still, they're doing the same thing with the Powerjack that they did with the Blutsauger.
And from what I understand, back then the unlocks were *supposed* to be upgrades. They just had a different idea as to how the thing would work when they started doing unlocks and updates.
They changed the ideas behind item unlocks, and they changed the Blutsauger with it.
Yet they do the same thing with the Powerjack now - I don't know about em.
At any rate, I anticipate a pretty major rebalance and bugfix update either this week or next week. As with every other update ever, there are several unforeseen issues that they have always resolved in the following week.
