I agree this is just frustrating. It's a fun game but every so often their are these things which just suck all the enjoyment out of the game. Let's just throw everything we have at the player so it's almost impossible to dodge or you have to wait for some item to spawn just to drag the fight even longer. This fight is a good example, everything at once. Ow and instant dead is never a good game mechanic. It's the same when playing a board game and drawing a card which says you loose. Not fun.
I work and can't spend hours of a day learning some fight or spend hours replacing gear because my current setup it's impossible to finish a fight. I already skipped some things but doing that to often it's just makes me think why bother with the game at all. Can't really imagine it's something the developers want to achieve. Even Star Trek Online did it better. An extremely grinding game but at least you could make some baby steps each session and the festivals you didn't have a pain in the kitten thing.
Sorry I'm just frustrated and had to vent because I like the game but it just to often throws some ridiculous things at you but behind that they're some nice goodies which I know I would never get.
