I feel like they should add EC and TFB SM in group finder as a tier two, and only accessible after you've done both KP and EV SM. Theoretically, forcing people to do the other two first would make them pick up some sort of skill/understanding of how operations work.
Obviously this would still require some judgement, but I feel like it'd be better than the current system. Even if they just added EC this way.
I'm sorry, but if you think that this would help them you are pretty naive.
Also what if they don't get a reasonable amount of gear from those two Ops and then jump straight into EC?
You can carry maybe one slacker in a PUG, but 2-3? Impossible...
