Sooo, Dash has this nasty donut hole at R1 when using HLC.
New Ionizing Illicit coming with Sabine's TIE will almost certainly work in R1, and is triggered "instead of performing an attack".
Sounds like a plan? IMHO it'll be much more action-efficient for Dash not to have to fully commit to staying outside R1 at all cost, when going gets tough.
Instead of EU, take the new Illicit, and Countermeasures. Then, if you won't be able to get out of R1 deathtrap even with BR, get focus for defence and TL for the next turn. Then pop Countermeasures, and bathe your enemies with EMP.
Sounds viable?
