Yes the Wang is very limited in it's loadout. You really only have one major decision to make - XL300 or Standard 225?
But it is a total monster on the battlefield. I used to swear by the 'slow wang' with a Standard 225 but after getting constantly frustrated by light mechs I traded some survivability for speed and I haven't looked back since.
Going 107kmph with an AC20 and 2x MPL is fearsome.
The Wang has some major advantages over it's contemporaries:
HBK-4G - has very poor vertical traverse for the AC20 and the side torso is harder to protect than the Wangs arm. Also a poor zombie as you lose a laser when the AC20 goes. No option for a high speed HBK with AC20 either.
CN9-A/D - SRMs are only effective at face hugger range, and often you just don't want to face-hug (i.e. a splatcat) or doing so would expose you to the entire enemy team. Wang can participate in peek-a-boo AC20 sniping out to 500m and still inflict reasonable damage. The SRM CN9-A/D is point blank only. You can bring a more flexible AC10/Gauss build (which I prefer) but that sacrifices speed or missles so doesn't really fill the same role as a Wang anymore.
Don't forget the 4 module slots you get with a Master-Wang if you are a fan of airstrike/artillery
Anyway there is no right or wrong answer, it really comes down to personal preference and what you see as adding the most value to your personal gamestyle. But it is certainly wrong to write of the Wang as not effective. Limited yes, but very much effective!
