BladeDancer and SwordThe singer was created by NCsoft for Auxiliary Party Buffs to the main buffs I hope they still remain
"SwordThe Singer" killed me irl. In this version of the game, contents are SOLO-based. Which means BD and SWS are no longer supports but pure DDs classes. And i like it. Did a BD and so far i'm really enjoying it. Hope it wont become trash later on. Even tho, i think that KR developers of L2 are in love with Elves, otherwise i don't understand why all the elves are getting OP every patch. SWS' songs are way way way stronger than BD's dances, in terms of bonus...like, all SWS songs are viable in PVP while BD has some useless dances like..."decrease mp consumption for skills" (we got clarity and mana recovery, useless), pve dmg -10% ('cause "damage -10%" was too good) and "buff cancel resistance"...like...who cares? there are literally 3 classes that may remove my buffs, why should i care in the first place? And if i think about Touch of Death, losing 1 or 2 buff is the latest of the problems.
To me the real question is another and I can't answer by myself because I'm not playing a BD nor a SWS. Do the BD and SWS buffs affect the whole party yes or no. Because if yes it's pretty obvious after lvl 81 you have to be part of a cp If not well it's pretty obvious after lvl 81 we will continue to do the afk bots.
You can't buff other pts member in any way, with any class. Even buffs such as Mental Shield and Resist shock from EE are now passive skills.
