Titan loot is based on the Loot tier you get (XI, X, IV, VII etc …) which is in turn based on the damage you dealt and the number of stars your titan is.
In truth, the more flasks you use, the higher your rank will be so better loot should be gotten (Getting A rank compared to C rank)
I’m running a titan loot data project to pin down the odds of getting various items and materials from titans. In this post I also link to an explanation of the titan tiers and ranks etc…
