I agree with Gooner, Events are far better than conflicts when you just want to unlock the Event reward and/or maxed out different units in a short space of time through the Bonus Crates. Conflicts are time consuming, too much effort and most of time ends in frustration when you miss the last days or can't get the high leagues no matters how much you attacked.
The reason I gave up of conflicts with my two Prestige, and now I'm giving up with my low bases if the thresholds are too high. I can't play conflicts with al my bases, but I can play Events with 4, 5 or 6 bases if i want, and stop when I get satisfied or max out the units I want.
I agree with Boog. 4 weeks is too much, specially if the 4th week rewards the same than the first week (TX225). 3 weeks are good if they offer different rewards in every week, and not as in the Naval Event when the 3 week rewarded Pilot like the first week. 2 weeks would be perfect, with less EP for Bonus Crates like 450 EP for 3 rewards like it was in Naval Event.
900 EP for a single Elite Crate is not a Bonus if you are running Prestige bases, it's more like a punishment, like the destroy 219 turrets and 315 buildings, or earn 790 EP during the Event. If it wasn't that much, I would play with my two Prestige even with most of these units already maxed out, and the Bonus Crates rewarding now only frags for Heavy shore/Gigoran, Senator Leia/AT-ACT and TXs for both bases.
