This applies to TLB, too, though.
True. Maybe it's emissive which needs a balance pass... maybe limit the effect to a relatively short period followed by a cooldown.
Which isn't a problem in this case, because if your shields are up, missiles won't hurt you anway.
Personally I got good results with point defence when I put one on top and one on the bottom of my ship, unless the opponent is really stuffed with missile launchers. This would of course completely disable him to fight anything else but hull tanks, so probably not the best choice. Pack hounds are an exception of course, but they are also easier to outrun.
True, but seekers are very short-lived. If the speed difference is not too big, they usually can't catch up in time.
I don't think it has anything to do with skill... it's a typical rock/paper/scissor thing... Seekers are useless against anything but hull tanks, which are only used by a minority of PvPers. And if you are in a hull tank, don't attack a ship with seekers... just as you wouldn't attack a ship with reverberating mines, when flying a slow shield tank

There's a lot of annoying stuff in the game, but we have to live with it.
Personally I'm using seekers on some of my more cumbersome builds (i.e Python/Dropship) because I don't like fighting agile hull tanks in them, so I bring seekers... if they attack me anyway, well... their choice. If that qualifies me as a noob then so be it.
