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.
A good tank should get less than 2 satchel charges. They are very easy to dodge. If the mobs dropped Rakata-level armoring, mods, and enhancements it would make everything but EC obsolete.
