If you have sufficient information, making an assumption can be the same as making an educated guess, which is the best that most of us can offer most of the time. I assume the stocks I'm holding will grow in value. I assume my girlfriend loves me. There's nothing wrong with these assumptions as I have conducted due diligence in both my finances and my relationship.

However, if I come to a conclusion or an assumption based on a feeling, a notion, or without exploring all the information I have at my disposal, I'm pretty much just guessing. And that can be fine, too, but I'd be an idiot to simply guess that a certain stock is going to perform one way or another or that the person I'm in a relationship with isn't a total psycho.

You give the impression that you base a lot of your assumptions on feelings and even when confronted with information that explicitly contradicts your gut, you're unwilling to accept the idea that you might be wrong.

Several knowledgeable players and staff members have explained why MotP functions as it does and that it's not the nuke against rangers that you seem to think it is, yet you don't seem to be making the connection that maybe the way you've interpreted the skill is part of the problem (your seeming inability to adapt to it being the other part.)

Also, it doesn't look like it's going to change, so what's your solution? Never fight assassins? Where's the fun in that? Don't forget that many, many assassins are played by the newest players to the game. You should be kicking their asses so hard that you feel bad about it and begin to just creep by them unseen. As for those assassins played by Isildur and the like, run, just run.
