Gash,
Wow is an MMORPG with PVP being available . Wow was not created solely as a PVP game. Breaking things, because of PVP issues, breaks the RPG part.
The combat log and add-on access existed back in original Wow and still exists in Retail. Blizzard has had 15 years for making API changes: They have left this capability.
You can play RUST, which I assume, is more “fair” than Wow.
