They can be "OP" under the right circumstances and with a good pilot in the cockpit.
here is the Dakka version with a nice match:

and here is a good version in the Dual gauss/ER-PPC version:
having said that though. it's also really easy to take them out in fast lights at the beginning of the match if you are a capable light pilot.
I've had matches where i took 2 KDK-3's off the field in my locust with 6 SPL's on grim from behind within 2 mins of the game start. with their hard points being that high, and the locust being so small, it's really easy to sneak up behind them and shoot the **** out of their backs with them being able to do NOTHING about it.
does that make the locust OP cuz you can take out KDK-3's without any problem if you get behind them? no it doesn't. it's all in how you pilot a mech and who pilots said mech.
Put an experienced pilot in any mech, and he can probably take out that KDK-3 with an inexperienced pilot in it.
Here is another example of a mech that is "OP" if ya know how to handle it.. the Warhammer-6D
and yet another OP mech.. this time said locust i took out those OP KDK-3's with.
and another OP mech
Mechs become OP in the hands of good pilots that play a lot and know maps, it's the Pilot that is OP, not the mech.
