Why, what did they do (I haven't played yet since the patch release?)
They killed them completly, im not joking.
I sold my SRM boat because of it they are that bad.
Think LRM flightpath with SRM missles.
They fly the same as they did for about 50 meters but then spread into a sawrm like LRMs and then at about 200 meters if you are targeting your target with R will converge again.
I would say at below 50 meters they hit with 80% of the missles as before, shooting at 100 meters is literally useless as missles are at max swarm size i hit with 4-6 missles out of a 24 volly at this distance, at 200 meters you will hit with 60% of the volly if target targeted with R, and at max range 270 meters you might hit with 30% of the volly.
Compare that to before when at less than 100M you would hit with all missles and even out to the max 270 meters would hit with over 75% you can see why this is an issue.
Why they think SRM's need to swarm is beyond me.
Now SRM's are only useful for scout mechs like commando's and jenners because you can get in their face and fire point blank. Facehumping people in a AWS-8R Awesome SRM boat however doesnt work out so well because of the hot air ballon sized cokpit makes it an easy kill.
The AWS-8R with nothing but 4 SRM6 racks and 10 tons(1000) missles was my favorite mech till tuesday, could be guranteed to get 700+ damage and at least 3 kills a match with it as long as we had a atlas to tank and distract while i got close enough to missle range then even a atlas would go down to three vollies.
Also rearm costs are, well, not good.
