I started playing MWO after the ECM patch came up. Consequently, my first was the 3M cicada...discovered I hate dealing with trying to strafe and fire ballistics, so I went with lasers and knife fighting. Then...I thought of how I could use a tag laser and/or ECM jamming to get a lock with streaks/be a decent spotter, so I got the 2D commando...at that point, my kills/deaths went up obnoxiously high (3 to 1 pugging). I'm not completely lag shielded (80ms), and I must say it's been quite fun. In learning to obtain a lock, I've finally become pretty decent at manual targeting, and running the cicada isn't so bad, especially since it is not as fragile and doesn't spend 40k in ammo every round.
Streaking with a light mech is certainly a good way to become exposed to the world of MWO
What I am most frustrated about is actually that I almost never have any significant LRM boats on my team. I equip a TAG instead of a medium laser, and the best games I have been in, it went so well because I was able to act as a decently difficult to hit spotter, while able to take the occasional SSRM pot shot, and run off the ECM lights, who go after the LRM boats. (I drop the ECM long enough to get an SSRM lock, and fire, then bring it back up if I am being targeted). When I survive to the last minute or so of a game, I am almost always 2nd for both damage and xp (half of my xp usually comes from spotting). Since I'm a noob, ECM must be OP.
IMO, the anti-locking/targeting ECM effectiveness needs to be relative to the mech tonnage and incorporate BAP, so the spotter role can maintain its current survivability and viability during an ECM nerf. Furthermore, maybe stacking 2 or 3 of them would be required for a light mech to be undetectable/lockable at the current settings, and 8 of them would be required for an atlas (allow stacking). Keep the close in disruption bubble the same, but change how guided missiles work by making them ballistic after entering the bubble unless the target is TAG'ed. ECM could also be an upgrade like Artemis, taking up slots and weight depending on which mech has it, though I like the idea of manually stacking it better.
