https://github.com/TrinityCore/TrinityCore/blob/master/src/server/scripts/Spells/spell_warrior.cpp#L1152 i don't know for the second answer

Ha ok i see :), and yeah i always change the cdns too but it's kinda useless !

Nope, didn't figuret it. TrinityCore have his own cdns/versions hosted somewhere ?

Personnally, i modify the both exes (64 and 32) with a hex editor program and change the path cdns/versions to my own server.
