Guild Wars 2

…apparently turns all the mobs invincible yet at the same time they remain hostile.

This is a horrible solution; if you want the dungeon to become impossible to complete, might as well just auto-kick everyone or physically block continuation and a message or make the mobs friendly (thus invincible but not going to steamroll anyone in the middle of one when a party member vanishes), but the invincible hostile mobs without warning thing was terrible design (first off, this was not known/explained before hand, secondly the person dropping out just vanished, without explanation, and I hadn’t even noticed – I didn’t realize what was happening until it was too late).

I’d also like my 1.98s for armor repairs back in addition to having this behavior corrected. Not to mention it also cost me progress on the ‘exp w/o deaths’ achievement.

What? I lost party members a lot of times (some times I even completed dungeons with 4 players or 3) . I have never seen mobs turning invincible.

Never experienced this.

Really? o.o Ok, well, here is a complete rundown of events:

1) join some party for an AC SM run
2) enter instance, I head in following some other people, loot a coffin, see some small spiders, take a swing at them: I see ‘invincible’ pop up and think, oh, maybe a collision bug, I’ll move back.
3) In the party chat, I notice that someone comments that someone else dropped out; lo and behold, there are now only 3 other party members (so 4 total including myself)
4) In the meantime, a huge swarm of spiders appears, so I swing at them again, and a whole bunch of ‘invincibles’ pops up, so I swing dodge and try to escape so that I can exit the instance via the entrance (I didn’t see the exit icon pop up over the map), but I get completely overwhelmed by the huge swarm of invincible spiders and die.
5) I respawn at the entrance waypoint, but rytlock happens to run by with the invincible mob + 1 ascalonian in tow as I respawn and I get destroyed again when I try to make it through the cluster again.
6) I respawn yet again after waiting for them to move away and then leave the instance successfully this time.
7) I complain to a party member about the mob going invincible and not realizing what was going on and he said ‘lol you didn’t notice?’ implying that he experienced the issue as well
8) I go pay for repairs and then exit, and vent my frustration over this issue on the forums via this thread and then need to go get some food to eat.

Since Anet apparently keeps logs of gameplay and chat in order to combat spam and bots, they should be able to verify this.

You make no sense. And it seems that you didn’t get far at all in the dungeon, if rytlock can drag a single group of ghosts to the spawn point. So stop whining and try again with a different group.

It made perfect sense. For some bizarre reason the mobs became invincible. It doesn’t matter where it happened.

Sounds to me like the group failed, brought spiders back to the entrance and they went invincible due to pathing issues. (Standing on tables or somewhere the spiders couldn’t get to)
