Most importantly than items, events guide you to reforge your experience of the game
For myself, after an event, my knowledge and strategy greatly uprised. thus making the game more enjoyable.
Yep,
Those Zahhak's gear are pretty cool to have but certainly not the optimum choice for some quests
Plus, from what i know, there is regularly events, so no need to hurry
I recommend Soloi, It's a nice one to show your progress. The secondary objective( 15min ) is probably impossible for a beginner but you can make your owns objectives.
For example.
first try: kill general
second: destroy first fortress
third try, destroy second fortress
and so on...
I did that...
