I got curious and performed my own extraction from the 'WWB_VGS_Engineer_Skin6.pck' & 'WWB_VOX_Engineer_Skin6.pck' files within Paladins, then discovered that I had 209 .OGG files compared to your 207 total .WAV files & 207 total .OGG files contained in the MediaFire link as found in Ethius Eximius's video that I believe you used as your Source.

I checked through them and managed to find the unique voice lines that were missing, then also placed them in the folders where they should belong (I haven't converted them to WAV though just in case I didn't successfully replicate your methods):

And just in case, here's my full extraction via Riveal 11.1[www.rshayter.com] (Which was also able to extract all of the files with their original file-names!):
