Not to mention that this doesn't make any sense from a practical or logical standpoint:
"Hey, you over there! I see you trying to hide from me...you're right behind that other group of people there! What? No, they're just going about their business. YOU'RE the droid I'm looking for!"
Exactly why this is such a big issue to me.
Stealth is supposed to be an advantage, not put us at a disadvantage for using one of our abilities. I have no problem with bosses detecting stealth, but I do have a problem when it often results in a wipe because the boss saw me even though I was further from the boss than the rest of my party.
