Guild Wars 2

Alpha 1 usually I just solo melee him to death. And Alpha 2 and 3 I would need group members to help getting me out of crystal from die zerging. I dunno but it seems really hard for certain spec and classes out there. Some say ranged is better choice but I definitely find meleeing has the most survivability.
But anyways, the boss mechanics is stupid enough. Literally it is just spamming 4 script lines
1. randoming dropping a lot of spikes on ground, no cooldown
2. randoming pushing out earth spikes, no cooldown
3. crystallize a person randomly, recast again after one down or got out
4. spawn essence to heal by a time interval
Once you find the way to beat these 4 scripts, then all you do it repeat what you do for a whole long fifteen+ mins

At first when I got in to SE this path and we have to deal with these 4 trashes we are like,
they constantly throw bombs at you with a big quick red circle on you, fine
they have strange aggro mechanics and like to focus zerg one person at a time, fine
they chill you once a while so you have to eat their big fat fruity bombs, fine
they have hp high enough to fool you (or wipe you) around for good 5 mins+ each, fine
so as we thought ok we can deal with all these and guess what,
THEY KEEP RESPAWNING FOREVER!
That’s when we call it ridiculous and sorry we aren’t gonna waste our time anymore.

My main is a 80 guardian and the class is mostly melee so I have somehow been trained to dodge and tank (why tank? Cos they always stick on me for unknown reason) most of the encounters. And I can almost 100% tank dodge champion giants and some explorable bosses. But the overall impression on dodge is like an offbeat note or a timed script button pushing rather than feeling real or fluid.
Why? Lets look at the giant. You do not dodge when his animation shows that he is stepping on you, its too late. You dodge when his foot is still raising up so when he step on u u got evaded pop on ur head. The timing and the animation just feel off. It’s like you got 100% in beatmania but all notes just sound 1 sec delayed.

Anyone feeling the same?
