Hmm, I'm not sure, I've been running my 9M almost constantly since the patch, and have gotten top damage on the team much more often than not lately.
The change to LPL is just amazing, though I think the main thing is that I'm finally running an XL engine.
3x LPL and 3x SRM4 with the missile tubes that the 9M has means that you have a 60 damage alpha that is almost completely pinpoint.
I've flanked entire teams and 1 shot a couple mediums in the rear CT, followed up by 2-3 more kills, even if I'm alone on their side. Sure that is their fault for not being aware enough, but nobody expects a freakin 80kph awesome with that kind of firepower to come charging out of nowhere.
Hell, I even decided to guard tunnel in frozen city one game. A jenner and commando came though, and I had no help from my team, but managed to kill them both. Once you get some practice aiming the SRMS at lights, they do some MEAN damage.
This is just an example of one of my better games, though the majority of them has me at around 500-800 damage.
As for the drawbacks of an XL engine, I've noticed that it's quite rare that I die from side torso destruction, and when I do, it's with such overkill that I would have died 3 seconds later anyways.
