Ok, here's my list of problems with carrying ToM to that fight: 1) It's intrinsic perk is mostly lethal for you since you run the very high risk of being killed by continuous damage from the gun plus that inflicted by ads and Aksis himself. 2) You waste your exotic slot on this one gun, which could be better used for an exotic heavy like Sleeper, Gjally or, yes, Dark Drinker. Those same exotics can help you kill captains faster without even wasting a supercharge. The same can't be said for ToM. 3) If you decide to switch primaries and heavies prior to damage round, well, yeah, you can do that, but it's always going to consume precious seconds where you can miss the opportunity to inflict dps or, at worse, get killed by anything during the switch. And...nothing else comes to mind right now. Simply put, there are safer and more efficient ways to do tons of dps on Aksis without risking your life using a gun exclusively made for and/or as a prize from the previous raid.
