QFT. Which is why the entire contest is utterly pointless.
Things I see wrong with the whole Jeydra vs Bright Star Shine "competition"
1. Shiroken comes in relatively small group, it favours Chain Lightning / Invoke Lightning...where their biggest weakness had always been "only hit 3 targets"
2. Shiroken monk uses reverse hex/shield guardian, shiroken mesmer uses shatter hex, shiroken ritualists have recuperation / life, every shiroken has song of the mist. It counters spiteful spirit / MoP...being able to spike with multiple air spells is a big advantage in that area.
Then there are issues like micro and tactics. There are TOO MANY VARIABLES not taken care of.
P.S. Bright Star Shine, told you that "its a trap!" in the other post.

Its a relatively balanced area. While individual groups are small (4), you can easily lure 2 together in about 75% of the situations, if they don't already start together when you aggro them. Moderate hex/enchantment removal isn't unknown for most PvE reasons and being able to handle that is important for builds. The only real thing messing up comparisons is that the rits actually have Restoration, which can obviously be a bitch and cost a good 10s if it lands in the wrong place. Its not much though. The important thing is that you can do repeated runs and just submit the best time. Micro is irrelevant, all players are allowed to micro obviously. Tactics are mostly irrelevant, Raisu is set up so that there isn't really any way to "cheese" it, unless you see an 8x Shadow Form team with each hero running and soloing its own boss you can rest assured everyone is playing pretty much the same.
Essentially, Raisu Palace is fair and representative of an average PvE area. Its probably the most constant area in Guild Wars in terms of spawns and how you can play it, its short so the variation won't be too large, and it is at about the mid-high range of PvE difficulty. Go ahead and point out another area, chances are I can poke a dozen holes 2x the size for each issue you have with Raisu. If in the end the disparity between two builds is something ridiculously small like 10s then its probably not statistically significant and we won't care, but its not going to be that close.
