It has a solid performance profile. The only big loss they had taken was against an ISD/ISD/Goz fleet with a half(ish) strength squad screen. Liberties are very abusive against almost anything, but two Liberties don't hold their own against two tricked out ISDs.

I would certainly agree that a Liberty can't really go toe to toe with an ISD. Although you have around the same amount of firepower the lack of defensive options can really hurt. It can get in some really good hits though, especially when supported by the rest of your fleet.

Except a Liberty with Madine, & an ET can get around an ISDs front arc, and over power its side or rear arc 7 dice to 4, or 7 dice to 2 if it is an ISD I.

Not sure why you think it needs to sit in its front arcs trading shots, it has the capability to run rings around an ISD.

I'm not sure exactly where I said you should sit in its front arc and trade shots. In fact I'm pretty sure that I'm indicating that you shouldn't. My main concern with the Liberty is that its not particularly tough which I can see as being an issue that I'll have to deal with. It's got a really solid punch thanks to it's front arc and available upgrade slots but it wouldn't be wise to consider it to be able to wade it to an Imperial fleet or ignore the fact that if you expose your side or rear arcs you could be really punished for it.
