My goal of this post is to get some MathHammer on the title's subject, now that 6e has changed things a bit.
As I recall, with 5e eliminating 'partial' hits for templates (4e's game mechanic), the submunition round surpassed the ioncan for MEQ killing, given that power armored goons tended to clump up more during 5e as they did in 4e, getting out of rhinos & drop pods. My experience at least.
With 6e's game mechanic of Focus Fire assisting the IonCan's AP3, where does the MathHammer now fall? I'm not number savvy enough to plod through odds calculations. Drift for the scatter, and all that makes my brain hurt.
Could someone help out with this? How many spess muhreens die under the following circumstances when shot at by the Sub munition Round vs. the Ion Cannon? (if you're good enough at MathHammer to include MarkerLight fun, then da-ang, go for it!).
a. The SM are in the open and reasonably clumped together, so 6 would fit under the Big Blast Marker.
b. The SM have some Cover. 3 or 4 do not. Apply Focus Fire
c. All have Cover (5+)
d. All have Cover (4+)
So, 8 different situations.
