There needs to be an increase in the quantity of fleet marks provided (or a decrease in the quantity required). And would it really be so bad if the Fleet Defence missions granted 400 Dilithium as well?
Fleet Marks should be awarded for specific fleet or group content, so they were not considered to remain in this new rewards structure.
I'm trying to locate the patch note when they were introduced, but I'm fairly certain that it mentioned they were for a limited-time or were temporary, or at least that was the intent.
Um...but some of the so called "fleet" events already in game can be played with a group as small as 5, and you can play foundry missions with a 5 man group too. So why take away something that was already there?
