Some hotfixes have now nerfed Normal and Heroic Silken Court.
There's one change that would effect all players on Silken Court. You only need 1 Binding Webs to stop the boss on Heroic difficulty. This change makes sense since the common Heroic strat was to not bother dealing with that mechanic at all in Phase 3 and this should make it easier and incentivize players to do the mechanic «correctly» to kill the boss.
This has been confirmed through a recent log.
Some of the other changes seem similar to the group size changes previously.
