Hey Jackson, did you send your tweak to MR. L's testing league? It would be interesting to note down the results.
However, the original shaolin 4141 didn't do very well even excluding 352WB formations.
Also, stephanhk created this formation (41221) as well based on his original 4141. Only roles different in your tweak is IF(a) instead of IF(s), and AF(a) instead of DLF(a). And your PIs for front 3 are minimal.
I have tried shaolin 4141, and it seems to play great counter attacking opportunities. Your tweak is better in attack definitely. However, why not add "Shoot less Often" to IFs as well.
Also, I will look to change IF(a) to IF(s) with PI "Get Further Forward", this way IFs attack the same way as IF(a), but more efficient while defending.
