Dual Blade Questions....

my friend had a question about DB's but i dont feel like making a new topic for this:

Do dual bladers keep casting darksight in order to not get hit by bosses? Dark Sight doesn't work on bosses or magic attacks......and they cast Dark Sight so often to use Chains of Hell and to take advantage of the invincibilty frames.

if so, doesnt it suck to have to keep casting it nearly half of the time? or can this be fixed by macros? what if you didnt get pulled out of darksight, but your macro casts darksight? otherwise you could just put darksight before every of your macro Advance Dark Sight kind of ruins the macro idea since it gives a chance to stay in dark sight after using Chains of Hell, but its not that hard to cast dark sight and CoH

also can DB's use SE from a bowman and Thorns together or do those 2 always cancel eachother?They don't cancel each other out but they don't stack either...

also, in the papulatus video posted above, the DB is only taking 2k ish damage, thats less then usual right? do DB have a defensive skill i missed?Nope o.o 2k dmg from pap is kinda normal.....he might have just had higher def/mdef

ok that where the questions of my friend, he sais thanks
