By the way, would like to thank Lillu for making the change today without nerfing, rather making the other options more rewarding. It's appreciated.
I'll post a full, honest review of the LDON system as I see it. I do this not to nerf the normal miragul collection tasks, but to maybe paint a better picture of why it is the only one a serious LDON points collector would run and hope that the others would be brought more in line with it so that the others might be used more. I think LDON is a great system and allows a more casual player/group to attain some very nice items at the expense of their time.
I spent a little over 12 hours (I am an engineer and love data - logged all the time I spent doing it) collecting 1500 points, which comes out to be slightly 12 minutes from port-in to the vale to the next port-in after a win (longer at the start and faster at the finish as I gained AAs and gear from other zones) using a group of 5. This just barely put it over my risk (time) vs reward to get mainhand weapons for my chars and would have much rather (from a standpoint of my sanity, not exactly rvr) been killing in Ssra/Kael. This does not count the times when I would just log because of characters getting hung up zoning or when I would simply log because of characters going into different LDON zones. I don't have much of a patience when it comes to that stuff. If I did count it, I would guess the average would go up to the 14-15 minute per run range.
Difficulty
I couldn't live through a two-pull on the only one I tried, but that was with lesser gear than I have now. From what I have read, much better geared people have spent an hour doing one of these.
Advantage: Normal
Zone
You have the choice of miragul or tak for normal, no matter which type you choose. The entrance for the miragul ldon is within spell casting range of the port in. The tak entrance requires a lengthy run across the desert of Sro.
Advantage: Miragul
Suggestion: Move the port in closer to the tak entrance and maybe consider doing the same for the hard ldon entrances as well.
LDON Type
Collection: Once you figure out where you need to go, you kill 20 mobs for 20 collection items (at least in Miragul). The mobs are close together and don't require much running to get to.
Assassinate: Kill an unknown number of mobs and wander around for a while until you find where the boss popped. I didn't stick around long enough to figure out where because I had already killed way too many mobs and could be getting faster points in other types.
Slaugher: Kill 60 mobs when I could kill 20?
Rescue: Honestly haven't tried, but I went with the assumption that it would be like an assassinate.
Advantage (although not 100% researched): Collection
Overall, I was happy with the time spent for my weapons, but it was only because of the specific combination of choices (normal difficulty, miragul, collect) that led to my time being used the most efficient way possible. If I had to spend a few more hours to crank out these points, I would have probably felt it wasn't worth it.
Edit: Wow, that was long. Sorry!
