[Sith Juggernaut Immortal is not a main tank]

You must be doing it wrong. I levelled 1-50 as Immortal Juggernaut, and I had no problem keeping agro from my companion, as well as the crazy DPS Sith Assassin I levelled with and his companion as well.

 

What level are you?

[Top 10 most powerful Sith and Jedi]

No Jacen Solo / Darth Caedus in either list?

 

I can probably understand Darth Caedus not appearing in the Sith List, but Jacen Solo was noted as quite possibly the most powerful Jedi alongside (and in some other ways, ahead of) Luke Skywalker.

 

Also not sure that Yoda would be on top of Anakin - Yoda's got 900 years on Anakin, surely that must count for something?
