I really have to rant now about this.
First of all, dear Devs: I have tought they adjusted "join in progress" so a kicked member can´t join that instance again?
Really, here is my experience from about 5 minutes ago.
Instance: Keeper of the Lake, High Roulette.
1. We start of with a CONJURER as Healer.
2. I pointed out he might want to put in his soul crystal.
3. He didn´t react to it, so I pulled the first 3 crabs.
4. He barely could heal up, as the only thing he did is to spam Medica2, even after all Mobs were dead, he spammed it until his Mana was depleted.
5. we cleared up until the Toad, when he was killed by the AoE... what a miracle.
First kick.
6. from now on, sh** got weird - SCH #1 joins.
7. as he approached our group waiting in front of first boss, and waited endlessly for him to protes himself, I did a ready check.
8. Ready was checked, but he didn´t go in with us... wipe.
9. due to lack of reaction, we decided to kick him as well.
10. SCH #2 joins...
11. I ask him, if he is human? with brains?... no reaction, no fairy, no movement....
12. as I start to move, i realize he´s on "Auto Follow"...
13. Kick...
14.... SCH #1 joins the group again.
Kick, abandon instance....
Seriously, is this how it works?...
