Yea but it requires many BoGs and planning too.
Ofc it is cool if u have to s/d only every 5 minutes.

It's not about brain, it's about that not every Sws/BD you will be in party will be 78 or even 3rd class.

That is right. And that is also sad

But imagine, you have fury +8time, fire +8time, vamp +7time and you broke vampire. You don't have enough sp to try it again, and then you're screwed. That vamp will get away too soon and you can't redance it cuz it will drain your mp down to hell. While cost will never take serious effects like that.
Or for ex. if you only enchant fire for time, that will remain even after all other dances/songs are gone and you have to start with fire or wait for it to avoid strong mp consumption.

Vitality has to remain and that's why only that should be +time based enchanted.

btw what u think about equickment?
I have on paladin rigt now TPA set and DLE crit. damage, its that good for sws? i wont buy new set:P

if its heavy and whith a shield it works the weapon also
as long as you will be a buff pet you can even go naked

look depends on ur role
u gona tank or u gona buff only
if u gona tank ur top a set works fine
even robe would work good if u are buffbot

dont forget that BW set is imba great for swordsingers(+7 speed and +song of wind=come and catch me if u can)
