Similar question to those of you who have experience: I remember seeing quite the number of demo/christmas tree ISD builds + rhymerball right before wave 3 dropped (what tourney was this at the top table mirror matched at? I can't quite remember). I never quite understood how those lists dealt with activation disadvantage, nor what the ISD is supposed to do with only 2 activations. In short, how are you supposed to play with that list? I imagine much of the strategy is applicable to double ISD's.
Best Imperial ISD builds
The +Rhymerball is the answer there
Mostly, its an overwhelming first strike, at long range, with a boosted comms ISD>
If howerver you tried to hang back, then it just waited, because it was ble to use Firesprays to hit you in the Squadron Phase anyway.
