Centurions are the quintessential sword and board build mechs. Meaning they excel at snapshot PPFLD weapons that allow you to quickly shoot and twist to present your shield arm to the enemy.
It doesn't do facetime/sustain builds well.
IMO, the YLW has been outclassed the moment the AH variant was released.
This is an updated classic YLW AC20 build

But the AH is far better if you do this

The ability to throw out 45 pts of damage and immediately twist and fend off most damage is what the Centurion is built for.
The fact that PGI put armor quirks on the weapon arm instead of the shield arm shows how little they understand their own game.
Side note, the A variant is one of the best training mechs IMO for torso twisting as it gives you 2 shield arms
The classic A build.

But this has since been outclassed by the SHD-2K, which also has 2 shield arms, but with more tonnage and JJ capability, and 1 more E hardpoint
