Shinsen-Subs subbed many parts wrong. Like when Cloud heads to Healin and Rufus says Ex-Soldier when he first rolls out to meet cloud. In the Shinsen-Subs version they say "....no doubt when you were one of the soldiers" when it's supposed to be "as expected of an ex-Soldier" There's also the part when Rufus says their at the capital of the Forgotten City Ajito in the Shinsen-Subs version they totally leave this out and instead replaces it with "their base" which does not make any sense at all.

If you want to get a good subbed version of FFVII AC go with either the very first release by Jasconious or with the newly release version by AonE.
