Seriously, i have no clue about dodging/using defensive CDs vs world bosses, if they are really huge and there is like 50 players around me. I can't see their massive attacks incoming, especially if i play with melee weapon sets. So how do you guys know when it is a right time to use dodge, Aegis or any other defensive CDs? And how do you know which of their attacks is a lethal attack? Sometimes they only hit you for about 30% - 40% of your health, next time for more than 100%. It's hard to track their mechanics.
