Could someone explain the new bard rotation?

[Egnasya]

It's less a rotation thing people complain about, it's more that Wanderer's Minuet buff which works like that:

Increases damage dealt by 30%. You cannot auto-attack in this stance.
Cast times are added to all archer and bard weapon-skills.
Can be used with other songs. Effect ends upon reuse.

Basically from level 52 onward Bards lose their mobility and become something like physical damage casters if you will. Up to that point mobility was one of the key features of that class, now it's basically gone. The other new actions Bards get either require Wanderer's Minuet or the classes two DoTs - or both - to be active to deal full damage, but aside from that everything is the same as before. Which also means that, while Bards have a nice chunk of support, their DPS is currently a bit lacking despite the mobility sacrifice and added complexity, and that made lots of people kinda angry.

Many would love to see Wanderer's Minuet gone I believe, but at the same time that's not very likely to happen since it would mean admitting faulty class design. Anyway, SE fixes their problems either fast or never, which means that if there aren't any large changes coming with 3.1 it'll probably stay like that until the next expansion adds even more stuff.
