Mono-builds and awful community? Are you sure you aren't talking about 40k?
Tabletop gaming will always be more random than within a computer or chessboard, for reasons i mentioned before but i'm sure your imagination can come up with more. The absence of this is exactly what allows chessmasters to think 20 moves ahead, similarly to DOTA/Lol/Hearthstone/Starcraft style games with your Rush/Mid/Late game concerns.
For this reason i think it's silly to get mad at GW for having a ruleset that favours randomness heavily, it's what we all signed up for.
