I respectfully disagree.
Please take a full tionese geared player on 8m HM xeno and tell me how that turns out. Even in SM tionese is under geared. Coloumi or better (with some augments) would be more appropriate for SM.
16m SM has an enrage-timer of 10 minutes
We were 15, some not even Rakata-geared and one or two people that don't know the difference between a lightsaber and a bottle of ketchup.
The boss was dead in less than 4 minutes.
