It would be true, after the slight change to ECM, there does seem to be less of it around (the close to 16th patch?) I will tell everyone what I told my team.
"The Stalker may be my favorite mech, oh no, I'll never touch it, but in 4 mans, everyone wants to run the new mech, and that means less ECM"
Try 8 mans, tell me ECM isn't around, I'll tell you LOLZ!
I also have this to say about Raven-2X and 4X
"Kill it as fast as possible, and don't let it hit you, we don't want the 3Ls getting master any faster than we can slow them down"

When you say you see 2x's out there, remember this, they are for the 3L's master tech, and nothing else, right now, there is no reason to bring a 2X over a Jenner-K (except if you want to run an SRM-6 with Artemis), and someday in the not too far future, you won't see any lights other than:
Jenner-F
Commando-2D
Raven-3L
The newest one.
Seriously, name a build, and I can tell you how they can do it better, even the few that the others can do better, is completely negated by ECM superiority.
