Guild Wars 2

in simin fight, first of all, you dont need to hit him while stealth just run the balls.
second, you do not need to kill him in two rows, just keep repeating till he is dead.
(seems that non stealth time is some kind of random timer, because we didnt find any clue when he is going to stealth, just that some times take longer than others)
you can buff yourself wich meals and potions.
we usually have a 5-10 min fight against this boss, so we pull, and we keep doing the mechanic till is done.
Also i know that arah p4, is not farmed, why? why i ve to spend 3 hours, in a dungeon to get the same rewards as i can get for doing path 1, 2 or 3 in half of the time. so doing path 1 and 2 in the same time as path 4, is better for farming, we dont have enought spare time to do the 4 paths (1-4) even on sunday, so why do it if not for fun?

time – efford vs reward is not balanced in some dungeons, arath path 4, CoF path3, for example are not done by almost anyone coz the are harder or longer than other path.
we do them for fun, but never had a thought for faming them, if we want to farm some piece of armor, we head to the easy ones because we want the piece soon.
maybe increase reward in the hardest or longer path will help doing them more often.

i ve done this weekend wich no problems at all, we have hard time to place the 5 sparks, however you need to keep doing it till you kill maybe you will need some practice at sparks and repeat the heal 5 or 6 times until you are able to kill him.
our group was, 1 suport guardia, 1 suport enginier, 1 tank warrior, 1 dps mesmer, and one dps thief.
there are some videos in youtube, where they kill simin just by doing the mechanic.
