Even if all the variants come from cbt i hope that the devs can at least consider adding gecm to the prime and the B variants, i just dont want them to end up as the harasser D and E (only harrasers without gecm i believe) who has a hard time trying to get close to the enemy unnoticed due to being spotted when they are 500m+ away from their targets.
Oh well, only testing them out will see if this will be a problem or not, but in my opinion the gecm is a huge advantage when trying to brawl and lightly armoured brawlers need all the advantages they can get, at least compared to the long range assets who can fight so far away that they can retreat at a moments notice even without gecm.
Well, consider that we don't want every mech out there with GECM, otherwise it'd just be... a GECM fest. Seeing as the prime and B variants aren't true brawlers (unlike some rapefist mechs/vehicles), and are hovercrafts, which by necessity are lightly armoured, I'd say the prime and B variants should be used by taking advantage of their speed for hit and run attacks, long range circle strafing, and cover hopping. I would not take the Epona into a straight up fight, but would rather hang back and hope nobody targets me. Instead of sticking GECM onto two variants, you'd just go passive instead.
The other place you see GECM is on scouts and snipers. Namely, the Raven, Harasser, and the Mad Dog. These guys want to stay out of the fight at all costs, but have enough spare "tonnage" or "win points" to warrant getting electronic packages.
