While missiles become useless if many people are on I must admit I have been killed by a missile LF in my titan.
Now it was in conn with about 50 people on and I didn't have much equipment or regens and it still took awhile. But I found that I couldn't hit him and he could spam missiles at me. I also found that a Firestalker is harder I thought to dodge with no cm's or cdt's.
In general missiles are impractical, someday this may change but today you might as well bag it.
