I don't see any Tionese tanks surviving the last fight with Lokin too well (tank is gonna eat some satchels), so I don't agree the mission is designed for that level of gear. This mission is listed as a Hard level 2, so theoretically everybody will be in full Columi before they walk in. If the mobs dropped Rakata-level amoring, mods, and enhancements the loot would be better balanced.
Did it on my Jugg in full recruit the day he turned 50. Granted the rest of the group was in better gear, but it's not impossible to do.
