I played this yesterday and I would like to hear some advices from all of you.
I played as a whm and unfortunately we couldn't clear siren. I was been blamed for by a DPS for not healing fast enough and to let my tank die when my mp was still full.
I felt really bad when he said that, but really there was nothing much I could do as during that point of time I was crippled n I couldn't cure/debuff my tank.
During our 2nd attempt we wiped again as our 2 DPSers couldn't escape from her dash, and each time their hp would drop 70%. And whenever the sergeants came out both my tank and I would have to run for our lives.
We did our part by watching youtube to learn about the mechanics before the game and had told them to focus on sergeants first.
