And if you remember back then, anything other than an Assassin was just a flavor build that no one took seriously. Heck, I was kicked out of some groups upon joining them back then when it was discovered that I was an acrobat instead of an assassin because assassins were only accepted because DPS is king in DDO. That's not the case now, but it was back then so old guides focused mostly on Assassins, although they are still useful.
Acrobats do grab aggro more than the other rogues, because Acrobats are hitting everything. It's been brought up by others, but the whole tree is built around jumping into or behind a group of monsters and hitting everything with cleaves and glancing blows then moving out of the way when you grab aggro. But aggro will be grabbed, whether intentional or not just from the stick fighting style.
