rogue evade function

[nwin]

I was in a group today and someone who had a rogue alt was talking with me about the /evade hotkey.

He said the following two things, and they were things I had never heard of, but wanted to see if it was accurate for P99, or later versions of EQ. Keep in mind, this isn't verbatim, so if the guy is reading this, I apologize for any miscommunication!

1) You should always open with a backstab, as you will cause higher damage then if you BS after you engage. He had a hotkey that was setup as /attack off, /assist, /doability [hide], /doability [BS].

I wasn't sure what doing Hide would do, since if you haven't engaged the mob yet, your hate should already be at zero, right?

2) Evade doesn't work if you have aggro. Therefore, he recommends evading prior to each backstab.

Now, this doesn't make sense to me. As I have had a mob attacking me, and then got a sucessful evade message. Unless it was timed just right that another player got aggro just as a hit my evade hotkey... I can see it as a way to lower hate prior to BS so you don't get aggro at all (I think of it similar to a Wizard casting concussion prior to nuking), but I think it would also work if you did it after you got aggro. Maybe he meant it's better to never get aggro (thus never getting attacked) rather than get it and get hit a few times prior to getting a successful evade off.

Thoughts?
