With so many personal goodies to buy, I can understand the feeling about Dil. That said, the reputation system in this game dose not have a steep playtime cost attached in my opinion.
One Infected Elite, about 15mins, and the Tau Dewa Patrol, say 20mins, will cover marks for the reps.
I work all day and when I get home I log on and do these things because it's fun. I have a great fleet with really awesome people, but I mostly do my rep stuff solo.
If your having problems accomplishing dailies in a reasonable pace, you might want to re-exam your skills/gear/ship type. My Engie/Tac Ody can do the deferi dailies, tank an infected elite, and smash the Tau Dewa dailie in about an hour. That's 3k dil, minimum, and roughly 60 romulan/omega marks...and some very grateful deferi ta boot!
The Reputation system has thrown a bucket of ice water on most fleet advancement, and least for the smaller fleets. It has stopped a lot of things, like making new characters, or playing most of my alts.
I am glad we all wanted a Tier 3 shipyard mostly, because tier 4 just may not come at all.
