considering the skills they use, mallyx is definately the most overpowered one
I always smile when I see what people in pve guilds say, they shouldn't forget that they're part of a small community
yes, anybody smart enough to run a basic build with 7 decent players can kill any of those bosses easily, they hit hard, they use lame skills, but they're just dumb AI
you should try to pug one time with a parangon for doa quest, I'd like to see if you manage to find a decent group in less than a week
ursanway is godmode, but you need godmode to beat mallyx with a pug, most people in ursanway don't even understand why they should not wand the monkey, use ursan roar or protective spirit... and most of the time you can't avoid them, because if you're waiting to find a good balanced group you'll spend one week spamming local chan
there's a difference between guilds that kill kanaxai in 26 minutes and people who don't even understand they shouldn't wand onis
