I don't have a problem with Siren's Reef, but I think the instability Social Awkwardness should be removed for the boss. Similar to slippery slope on Deepstone or Shattered laboratory, Social Awkwardness just makes the Siren's Reef fight artificially difficult. Either that or make the wind AOEless wide because there's just not enough space to stand. If someone gets blown off the fight is usually over. At the T4 level.
