Something to consider would be using "ingwie" the unique goshawk with decoy and equipping her with ECM suite. This makes her "unshootable". A bm ruled that since decoy and the suite check at different times, the only way to hit her is a critical or a melee.

Your BM ruled incorrectly then.

ECM and Decoy are both defense stat gear/SEs, so in order to use one, the other must be turned off.

ECM is not optional, therefore it cannot be turned off, and the Decoy on the dial is automatcially 'off'.

Even if you could get both to work (with Decoy gear), note that the rules for Decoy read that the shot is a miss ONLY if the second roll (reroll) is a miss. Since there is no reroll, the first attack roll stands, as a hit.

We e-mailed the judges and asked about this at Gen Con this past year and they both said that it works. The decoy checks after the first roll and then makes them re-roll and THEN the ECM suite checks and says that they are unable to re-roll their dice thus rendering no hit. They can work together because of this difference of when they check. The current ruling is that you cannot have 2 gear that check at the same time. i.e. armor does not stack nor will PPC Cap//Pulse

ECM effectively negates your decoy. If you cannot roll a second time to try for a miss, then the first roll stands which was a hit.

From the Rules sticky:
10. When using Decoy and ECM suite together, the second attack roll forced by the Decoy SE can not be made due to ECM Suite’s wording. In denying the second roll, ECM Suite means that this effect does not happen and so the original attack result (a success) will therefore stand.

my bad, thanx for the corrections

Yeah, because then ECM would be kinda mean and broken...

There's a difference between RHDM and simply immune to enemy ranged fire. It's actually a pretty marked one to me...

she wouldn't be invincible. you can still crit her or hit her in close combat

I'm aware, but critical hits are never to be counted on, and close combat isn't always the best of options. After all, you can CC or crit-hit SAD too, but because it's dang near unshootable, people hate it. We're talking actually unshootable here...that's not good >_<

You mean like Seismic Dampeners?

Players hate things that take them out of their comfort zone.

i agree that it would be almost fully invincible but ive seen plenty of crits, including some that have taken out the posiedon and a full health solitude

but on the flipside, i have seen ppl shoot 7 times total in one game...5crit miss and 2crit hits (his last two shots)
