Oh, and you include the Gun Mages he mentioned in this statement?!
Of all the shooting infantry I know, I do think these are the most "all comers" guys. With RAT7 they hit DEF14 more or less reliably and with a possible range of 14", they often enough hit DEF16 more or less reliably. They ignore stealth (you DID take the UA, right? This could just as well be a 7 model unit that costs 8 pts). They have magic weapons, thus ignore incorporeal. They can even deal with heavy armor (which you didn't even mention) by just pushing the models back or knocking them down. By now, I have killed Tartarus three times with a CRA from the Gun Mages.
Unsupported, it doesn't get much better than that.
I have played against huge Cryx swarms and I rarely have a problem with infantry masses when I play Cygnar. I would definately count our faction as "infantry mulching"
Apart from that: I do think, that Cygnar will get back a few of its problems, once all the other Colossals have hit the table. We certainly did have a problem with high ARM lists before stuff like the Stormwall and the Minuteman with its high POW cannons came out and with a meta shift towards Colossals, everyone else will put their heavy hitters on the table, which also pack a high ARM stat in most cases.
Apart from that, I'm pretty impressed with the stuff we got in Colossals and Wrath and I really think, Cygnar got a little power boost overall.
