How is the skill of the average wot player so poor?

Ectar:   Map guides.   I see a lot of people do tank reviews but I don't see people do map guides showing the common hotspots or where to go depending on the tank you're playing. Lots of people don't know that heavies need to be in certain areas to be zone denial or to brawl with the other heavies.  Many medium players don't know where to flank etc.   I'd love to see a youtube channel do a video series with map strategies. I'd expect it to get lots of views.
