The tier in a defense mission yes. The reward pool is dependent on the starting level of your enemies as well as which wave you complete. The longer you progress, the better the reward pool. Some missions (lvl 25+ starting level) automatically pick a reward from the highest tier pool of rewards as early as wave 5 (Narcissus in Pluto is a good example).

For survival rewards, the reward pool is dependent on the starting level of the survival level. I'm only sure about T3 rewards though, they are on survival missions where your enemies are lvl 15-20 at the start. Reward pools are different for 5, 10, 15, and 20 minute marks for different tiers as well.

okies thanks. i'll use this to fine tune which missions to do for mods.
