Okay so how come 90% of the nightblades siphon dots cant be used on bosses in pve dungeons........... i had an enitre warlock dot based build, yet becuase of the cc and slows that come attached with the DoT, bosses 100% resist the ENTIRE ability, it does ZERO dmg because it cant be used on bosses.......2 main dots for siphon......cant be used...WTF is that about, my god this needs to be changed ASAP.....

Well, the first ability is a HoT, not a DoT. And even if it worked, they over-nerfed it last update, so it's junk now. It actually used to be very good.

Sadly, I had the same type of build in mind, at first, myself. But then I found out siphoner isn't really a DoT class. You need to go DK for that...
