I'm using the r4442 downloaded from curseforge at this link https://www.curseforge.com/wow/addon...020709689%3A98
I know some players use the r7005 and both are for 3.3.5.
I never used the last one, the only difference I noticed by checking both directory is the r4442 is 3.91mb and the r7005 is 11.4 mb.
What does the difference of about 8 megabytes do?
