._. Like, only if you're an uncreative developer that thinks new = more powerful.
What are unique mechanics.
Well, let's look at it this way: If the new bases/assemblies are weaker then what you could get with a combat knife, there's not much point in the development time put into it, since you can pretty much always get a combat knife. If they're stronger then what you could get with a combat knife then it's a buff - and also a bit of a waste of development time, as you get the chainsaw on dlevel 5.
And if it's stronger then what you can get with the chainsaw...

Yeah, let's not go there @_@
If you're talking about Ao100, perhaps what could be done is increase the weight of the chainsaw - as it stands the min dlevel is 12 and the weight is 3, meaning that it's got about the same chance as spawning as the inquisitor's set and even less likely to spawn then a nano pack.
If that's not good enough? It's a challenge mode. >:(
Note that the note on the Ber/Iro interaction is a bug in 0.9.9.7 and is fixed in 0.9.9.8.
Unless I misremembered.
I am okay with this.
