It seems like the ISD1 is about to get totally upstaged. It's been nudged out of the supercarrier role already by the way-cheaper Quasar Fire. Since the QF, it's been almost exclusively used as a close-range brawler, particularly as a BTVenger platform.
In Wave 7, though, I have a hard time imagining the ISDK not completely superseding the ISD1 for that role. 5 points more for ExRax and replacing a red with a blue in the side arc seems like a no-brainer to me, particularly since those 5 points also buy you a defensive retrofit without burning your officer slot and a unique to bring Tua.
So, unless W7 is also bringing either a turbolaser upgrade that's super amazing for the ISD1, or an off ret that goes amazingly well with it and needs a second off ret slot (for example, something that turbocharges BTVenger), I have a hard time imagining what I would use the ISD1 instead of the ISDK for.
What do you guys think? Does anybody see a continued role for the ISD1, or will it fade into obscurity like the AF2A?
