Right now we see the rise of these super ECM hunters that appear out of nowhere and wreck havoc (which I believe is completely against the original intiention of the MW world). Here is perhaps a simple solution (though it will be met with great malice by some) -
Keep the ECM mechanics the way they are (I think they are fine).
Remove the ECM from the Atlas (sorry) and force ECM mechs to play their proper role by increasing the tonnage of the ECM and/or perhaps even better - reducing the number of weapon hardpoints on an ECM mech down to 2 (allow it to be able to defend itself, but not be a mini-ninja assault mech). Also have some extra bonus points in the scoring for the scouting role.
Just my thoughts.
