First, agreed, this "should" be on an individual "counter." It is a grind, to be sure, and as such challenges a lot of players, those playing casually, from the onset. But frankly, I prefer the grind to character/ account restrictions as we've seen in the past, so I'd pass along an attaboy to dev on this one (in this case I'm sensing an "attagirl"). I've also seen posts complaining about the reward being yet another robe, but again I see it as another attaboy for dev, it's applicable to all characters and all races, and considering all the restrictions that do exist, my vote is well done. One of my biggest complaints over recent years has been a disconnect in how dev "sees" the game comparative to those of us who play it. There's no disconnect here so again, attaboy. Major attaboy.
Dev can't code behavior. But they can observe it, and for the handfull of them who are/ were players first, the "intrusion technique" does occur and should be rectified. It would also be nice to know the "max" number of crystals required, we've seen posts saying folks have gone as high as 73 sans robe. My read from NPC dialogue was that 60 was the max, and each time I've turn a turn in, that was the amount I had available. Had I dropped 60 with no robe, frankly, I would have been furious. Imersion is one thing, infuriating players another.
JC mentioned doing turn-in in Fel, but so many folks simply are not going to accept that as a viable alternative, they shouldn't have to, and for that matter you're merely inviting a diffrent form of player intrusion. A different technique, the one I'm using, is to turn in with Leto in the Solem Hives. It only works with multiple accounts and preferably multiple computers, and requires a hiding character who tracks, so it may not work for everybody. I watch and track before going to do my turn ins. Still there's no guarentee no intrusion will occur, but it's the best I can come up to mitigate risks. Now that it's posted on a public forum, there's likely more risk than before. I'll update the post if suddenly Mr. Jackass shows and waits. Check first.
Hopefully, dev will get a fix coded for this quickly. The event, though a grind, has been well done. Let us know the max number required, or if there isn't one, just say so please so we're prepared. Walk the dungeons and clean up the errant sparklies. Set individual counters. Please!
Update: Yup, a post here and our first two asses are now camping/ intruding on others at Leto. I'd post the names but that would probably violate the TOS and nobody on Chessie would be surprised anyway! Just be forewarned, check before beginning, some people just don't ply nice!
