I've done some research on the optimal Slark build so that I can start learning. But I came across a wierd problem I have never ever encountered before.
Every Pro player that dota protracker shows are good on slark, do not go the same item progression. and somehow they are all good slark players.

For reference:

• 23Savage – Always Falcon Blade -> Always Diffusal -> Always Aghs

• VTune – Always Diffusal -> Always Echo Sabre -> Always Aghs

• Watson – Sometimes Falcon Blade -> Sometimes Diffusal , Sometimes Echo Sabre (Always Skip one of the two) -> Always Aghs.

• Ame – Always echo sabre-> Always Aghs (Never Diffusal)

• Cooman – Always Diffusal -> Always Mage Slayer (doesnt even make echo sabre first) -> Always Aghs.

• Yatoro – Sometimes Echo Sabre, Sometimes Midas (Never both) -> Always Diffusal -> Always Aghs.

• Pure – Always Echo Sabre -> Always Aghs (Never Diffusal)

Every Player seems to have a unique build and none of them sync up.
What can be causing this, surely it is not a game specific build since they almost always go this item progression across multiple games.
