It's the pilot. There's no perfect hard counter to a Raven 3L - thank goodness. That said, the closest counter to a Raven 3L is:
A jenner 3F with 6 ML or 6 SL can kill a raven. JJ's make the difference plus extra lasers for extra dos = win. I can do it with just 4 lasers - JJs are OP. JJs let you decide when to engage and when to disengage... Don't underestimate this...
(Also, If you're lucky and get a crit on the ECM, in the other jenner variants, your streaks will be enabled and the duel is essentially over...

It's funny to see ECM pilots stay in the duel when their ecm is destroyed... rare but it happens... don't tunnel vision when you can suddenly fire your streaks.. it can be the difference between the raven getting you.. and you getting them... )
A cicada 3M, with 4 ML or 4 SL, max armor, max engine. Counter plus more armour = win. (Cicada's are generally considered a light mech.)
A cicada 2A with 6 ML or 6 MPL - extra armour, extra dps.
That's considering light mechs...
Other mechs which are can counter a Rav3L are mechs with streaks (once the pilot gets within range .. ECM delays lock but doesn't prevent it in the 180 - 275 range... if you're not careful a streak cat can still kill a raven in 2-3 shots.. remember JJs are OP... ) KaoS's ace guass kitty pilots reguarly kill lights who get overconfident ... our assault pilots position properly and can take out a light pilot...
As a light pilot, I know when I face an ace pilot in a mech that can one-shot me so I avoid them and wait for a moment of opportunity. (It's the little things that define an ace... of course, sometimes you're dead before you have a chance to disengage, but "dems da bones".. scout and survey well in order to identify the better pilots..) I also know every counter to my mech - every place on the map that favours me and doesn't favour me... and why and when.. etc...
If you're having issues with a light mech, it's pilot skill and knowledge.
