The elites spawn DURING snake stage, not after. It spawns as the snake takes damage, regardless of rounds. Thou since it can only attack idle player, if you are still in your 10 rounds, they do NOTHING.

They are only a hindrance to completing snake and are not important in and of themselves. If you can burn down the snake without fighting them, everything is FINE.

And that's why they active attack players, because if they don't, they can just be avoided and won't do anything.

What purposes do they serve then? Hinder your chance at killing the snake. For one, they tie you up, so wastes your time. For another, if they defeat you, you lose a snake chance. So if, for example, you came late and have not attacked the snake at all but they have already spawned. They jump you and kill you 3 times. You are out of luck, you don't get to attack the snake at all(I'm not sure if you get any reward for having 0 damage done, you are placed onto the ranking for entering the summon zone so you might)

The first time we did the new summon, we almost didn't finish. Vast majority of us were wiped before we could form teams. And the remaining two players had to form a team and, due to them continuously attacking them, had to clean the entire field before hitting the snake again. We completed snake like 50 seconds before deadline.

So while the unable to form team in snake instance is probably a bug (or design flaw) the fact that they seek you out is integral to their function, or they might as well not exist.

Did you get attacked by the ambush ninjas? If you fight ambush ninja and LOSE, you lose an attempt.

Yeah, the fact that we can't from team while in the summoning zone, which makes teaming up unnecessarily complicated. Can you forward that as a bug?

Given that it's a message that flashes across the screen for a fraction of a second....

And also the fact that group summon is a collaboration effort and I can't very well take time out of it to collect such thing for you at expense of not helping out in it...

No, I can't.

But I WILL tell you how to reproduce this bug.

Step 1: schedule a group summon

Step 2: Enter the group summon with your character along with that of a group mate

Step 3: Try to invite said group mate from step 2.

You can do this in stage 1 of the group summon, it's the same throughout. You will be told that you can't form a team.

On the other hand, team is allowed, proven by:
Step 1: schedule a group summon

Step 2: Before/during the group summon, form a team outside the summon interface (note this can be inside or outside group base)

Step 3: enter the summon area as a team (leader can do this)

Ergo, team is allowed, therefore not allowing to team up in summon interface shouldn't be intended as it's self-contradicting.
