monk as a primary smiter?

Why doesn't Anet jus step in and say, "look, these builds arent' optimal so no one can use them. Now you can use build A B or C. Period." Why? because that would make the game utterly boring, which is why I don't feel the need to use only the most optimal build there is. It separates the good and bad players from the terrible ones?

Warriors play generally the same two builds.
Monks play the same two builds.
Rangers the same build.
Sins the same two builds.
Mesmers, more diverse in builds, but presumably and quite often targeted against a certain class.
Necros, MM or SS.
Rits, I really haven't encountered more than a couple in PvP so I can't say there.
Eles, same two builds. Seriously have you ever played pvp other then RA and AB.
I'll point out just a few common builds but honestly theres more then i'll bother to type.
First
Warriors->so many builds here. Just because you see a ton of shock axe running around means little look at high end gvg I see just as many sword and hammer warriors as the cookie cutter shock axe.

Monks->O.o Woh/Infuse->Blight(either mo/me mo/a both play diffrently)-->Rc Prot--> AoE--->DB(Dropping off now) and other modded ones.

Rangers-->One build O.o o.O O.o??? Cript Shot, Melh shot(spike).Melduras arrows, CG, Apply posion/Posion arrow, Full Trapper, VIM, Spirtspammer(kinda died recently).

Sins--Shock/aod base gank, Floursh, Temple strike, shock/morbious, Coward/fearme, and more based off diffrent elties.

Mesmer-->main builds but to say they only take out one target is stupid as many skills are multi functional. Take blackout(godly skill) can be anything from draining adrenalin to pre spike shutdown.

Necro-->MM SS you sure your not thinking pve. About the main over used one in pvp is bloodspike but their used for others heavy degen/hex overload--->Tainted warder-->there are really tons of mods in the degen are though.

Rits---> starting to come out into pvp but after spirt spammer nerf not many. Do see some restoration rits recently though and a couple spikes.

Eles--> Lots here though people try to combine them to save party spaces. Flagger--->Snares--->Shock wave warder---> Starburst And many diffrent ones which are uncommon but effective like a PD Ele.

Pvp offers much more open types.

Now PVE
Warriors--Tanks
Rangers--Barrage w/interupts
Mesmer--not mainy but tend to run surge or interupts when I see them
Ele---Echo/gor MS nuff said
Sins--Not tons mainly due to none partying them.
Necro--MM/SS
Rits--Restoration(spirt spaming is dead)occasional channeling though asked to switch to restoration
Monks--
Monk joins
Player--You heal
Monk yes

All computer games are based on math at the primary level. What is not fun to me is looking at a game as a set of numbers, rather than a role playing experience and an adventure. If only GW was a roleplaying experience, instead of the luck, skill, and numbers game it is.
