Frontier Hunter events go on for (roughly) two or three weeks, and are then closed for (roughly) three weeks. At least as far as my observations have gone so far (I'm level 71, so, I've been around awhile now). The event closes, and awards are given based on personal rank within the event, as well as for global rank and other factors - it takes the developers awhile to get all this info in, as well as determine if anyone earned there spot through cheating (sadly, some people manage to do that).

When the event reopens, your Hunter Rank will remain the same, however, your personal achievements (except rank) will be reset, allowing you to aquire rewards for beating certain rooms, getting a certain number of points, and so on, all over again. I do agree that it's a bit of a downer when Frontier Hunter is closed, though. Gives me one less thing to do on the game, so, don't get as much time to do things in the game (energy runs out fast).

As far as Idols go, the easiest (albeit inconsistant) is through "Paradise of the Fairies Lv.3" (Vortex > Enchanted Paradise > Paradise of the Fairies Lv. 3) Normally, this weekly event is only available on Tuesdays, but it's currently available until 1AM Pacific Standard/4AM Eastern Standard Time (GMT-8/GMT-5) due to an evolution event going on this week.

Based on my observations about capture, however, I've pretty solidly confirmed that killing the Idol first (or last, or middle, or whatever) does not matter. At each stage, it seems pre-determined as to which unit (if any) you will capture. However, in Enchanted Paradise events the capture rates for Idols (and Nymphs and Sprites) is greatly increased, and even more greatly increased for the 'boss' round (but still not 100% - It's roughly 85-90% for the boss round).

I found this information by repeatedly force-crashing my game whenever I didn't catch the unit I wanted - roughly 60% or so of the time, you'll pop back right into that round when you restart the game - every time, no matter which order I've killed the units in, and no matter how much overkill (or lack of overkill), or if I Brave Bursted, did not matter. The exact same unit (if any) was captured every time. Leaving me to believe that the unit captured (if any) is determined the moment you start that "room", and the only real variables are loot and BC/HC drops.

So, sorry to disappoint you on that one. But, best of luck to you on getting the units you need for evolution and, welcome to the wiki.
