I'd boost the LG to 6 and try to find a piece of ADV EQ that is +1 LG. Then at lvl 40 you'll be +10 LG. Or do the same thing with pancake. Either way I'd invest in SAs now. I don't think a C needs to 2nd cap AGL. Your build should be very competitive if your playing relatively equal level players for right now. I'm not one that thinks a C needs to 2nd cap AGL. But I think by about lvl 42-44 you'll want the SPD to 48 or 50 and the AGL to about 55. And you'll eventually want VIS and CON to about 50 as well. But being a C you'll hit those numbers easily and even if you build attributes above that, your still going to have a lot of SP to spend on SA. Cs just havea natural advantage. They need less AGL and SPD than other Oline and there lvl gains in BLK and STR give them an easier route that allows for a lot of SAs.
Impressive build though man. Do you have all 26 pts from EQ in STR? That would be great.
