If you're not getting that you're doing it wrong.
Know the map, NEVER be alone. EVER. If you're running off alone to 'provide support' you're dooming yourself. Stick at the back of your team, go where they go and provide fire support. It starts at range but it may end up being at 200m. Have either 2 ML or 2LL for a backup - anything less than that won't drive a harassing light off. Have TAG. Use JJs to keep lock. Use advanced target decay. Watch your team scouts; people can get drawn into chasing a Raven or Jenner out far enough from cover that if you tag them, fire, JJ and hold tag before they get into cover you'll get your missiles on target.
Don't get kill-hungry. LRMs are a support weapon. When someone gets to an orange CT, no armor and runs for cover, forget them. You see them out in the open again later, great! You're at your best however chewing on enemy snipers so they stay behind cover and allow your own team to advance.
Have 1 of your LRMs on a seperate fire group (mine's normally 4, which is my L-CTRL). You see a light harassing someone on your team? Drop an LRM on him and he'll pull off.
LRMs are a support weapon. Use them like a support weapon. In the current meta they are inferior in the most competitive 8man matches to a Highlander 732 with PPCs and Gauss, but otherwise they're a rock solid platform and work great now. They are better balanced than they've ever been.
Edited to add:
If you improve LRMs then players who are already good at LRMs will go back to pugging at a >5KDR. Pretty much you kill everyone, every game, until you drop in River City. Then you *might* lose if the other team is smart, which they are not always. Then you go back to killing everyone.
