spotter is insanely good, it allows you to make stuff with a BS roll nobody else has. delay -> wait for opponent to dodge -> spotter + standard attack -> +40 BS (without range or red-dot) giving you big chance to score 3D10+4 dmg, while your buddys run around with 1D10 + 2 weapons.
you can also shoot then stealth with the spotter bonus of +40, or make +40 called shots every round with deadeye shot and a targeter or the sharpshooter talent (for 300exp?). Honestly I as long as you are fighting orcs (which we are) I woudn't even bother getting the anti-dodge skill.
and like I said earlier in this thread: with the standard chameleoline cloak I make stealth rolls with +20 cloak +10 size. now that I got stealth to +20 I am basically invisible. and if the opponent should ever notice me (which he won't due to the sound supressor), he gets a whooping -10 prone -10 size -30 cloak = -50 BS to hit me. If he runs towards me, he is as good as dead.
