Also for those who didnt notice, Esseles you cannot use your speeder at all, but on Black Talon you can use it all the time. This is quite unbalanced if you ask me.
The weird thing about it that it's a relatively recent change; I think it came with 1.2 or later. You used to be able to use your speeder throughout the Esseles but not anymore. I don't really know why.
I still don't understand why Ironfist is considered the hardest boss there btw. Lieutenant Isric was way harder - although by the looks of it he's been nerfed. Ironfist was and still is all about interrupting headshot. Those who take three commandos to the fight have my sympathies but otherwise they should be able to interrupt every single one of those headshots.
