On Basilisk Droid, our Republic guild runs a min 4 man team most evenings and completes the daily in around 45 to 60 min. We convert this to a public Operation and often pick-up other players.
If you try Ilum open world on your own, you will get ganked and it will take a lot longer to complete the daily. Group up, get organized.
If you try fight your way out of the Republic base, you will most likely be ganked and it will take a lot longer to complete the daily. Get your group together and use the speeder to get to the eastern and northern pads, stretch the Imps out a bit.
Yes we often encounter the horde or a good group of Imps, but take a good number of them with us when/if we die. We equally do our fare share of imp ganking. Learning the map, use its design, stretching the Imps out a bit with some gorilla warefare results in smaller pockets of them darting about looking for us and taking points back.
In our opinion Ilum is working far better the prior to 1.1.0a.
Group up, get organised, and apply some strategy, and you may find yourself enjoying Ilum.
