The area of effect damage does WAY too much.
On Atlantic, where there's actually a population of players, it's nearly impossible to avoid given the LAG that it causes. The 5 seconds ends up being about 1-2 seconds of running because moving is like molasses it causes so much lag. At times, it's impossible to get away from the area damage from either lag or amount of players.
Your problems are specific to a crowded shard, the only crowded shard afaik. That's no reason to gimp a boss that's perfectly fine as is for everyone else.
I do the LS and Atlantic ones 5pm and 10pm. Both shards manage to them. Oddly I've only seen the tree and automatron.
The players on Atlantic will res you pretty quickly.
This lag is not Just EC, I'm on CC. I'm ok with the 2 second lag at each commanders death, and at the Bosses death. But the rift guy really makes a lot of lag. Maybe all the dead bodies. It's not like we can run to cause it.
I play ATL and while the construct can be frustrating due to players kind of griefing each other by running near someone (only worried about their own health) to kill them; I don't think it needs any major change simply because ATL is just so crowded.
The only small tweak I'd recommend is to one of two things.
1) Have the energy circles have a certain range (similar to Anok's energy voids) rather than unlimited range. There have been a few times where I have died and either been rezzed down by the bridge or have been running back from the healer and get taken out again because 2-3 people are running by. I think 10+ screens seems a little far to suddenly receive damage.
2) Leave the range the way it is but decrease the damage the further off screen from the Rift Construct; ie if I'm 10 screens away the damage is only 1hp versus if I'm on screen it's the usual 25-35hp
I didn't know about the healer in mistas the first time I did a crowded Atlantic. I went to the other one. I was returning and got hit by the area attack at the catapults, took me to 12 hit points from max.
It's annoying but I got a drop. Next time he appears in a crowd, I'm just going to tell the pet to guard, then die and not res until it's over and see if I get a drop.
I just did Atlantic with the Riftbreaker. My archer shot off 5 arrows and I died. By the time I rezed, the Boss died and I got a Goodie bag.
I don't see numbers above my head on Atlantic, when the crowd is large, there is a 2 second lag and everyone dies. I was standing off screen in the last picture, I knew the event began because all of us in that area died. Non of us attacked it from that far away. I ran over to the middle and pulled up his bar and took the picture.
But I get a bag. Like I said, I'm just going to die and stand at the healer and I'll know it ended when I get the bag. This is the 4th time in a row that Atlantic got rift guy while I was there.
When it starts on Atlantic the only tactic when it is him is to go to the healer over and over.
The crowd was smaller the first few days, this wasn't so bad.
I really like this boss, probably one of the funnest times I've had fighting a boss in UO even if it means me dying a couple times. I hope they wouldn't nerf it. The only way to make this fight funner is spawning 2 or 3 more Riftbreakers at the same time.
Okay, even though Lake Superior keeps rocking the event several times a day with a lot of players, it feels like we are being punished for something we've done, because the Construct keeps turning up multiple times a day.
I chuckled at the idea of the Benny Hill theme/Yakety Sax playing as we all ran away from the Construct and then ran away from each other, but now I believe that the Construct was placed in the game to make sure a lot of us will not see our Lady or Lord titles again until September.
Riftborne Monstrosity is not one of the bosses of Mistas, it's the Mawlings that are the bosses of Mistas.
