Horrid Twinning run as join in progress DPS. I only found out what the issue was with the last boss. Tank just willy nilly'd the fight -.- (I came in after 2 previous bosses). Time dilation beams, he just kept touching them, leading to needless healing from the AST. I think the SAM was worn out, the fight was already past the 60min(60/90) mark when I got in, and he started touching them later in the fight X_X. AST ended up tanking while I had to get the SAM and PLD up, btw PLD totally didn't provoke. AST survived because she knew how to AST well.
Twinning: Arena of blood and death.
AST /comfort me at the end LOL. I was saying to myself "I mean... you earned your comm when you tanked the boss better than the tank..."
Also she ended up tanking instead of one of DPS because I died earlier, SAM been on the floor for awhile, and so she topped the enmity list rather easily with all the heals being thrown out.
