Training modes for different aspects of the game

I was thinking the other day about making specific training modes that help players sharpen their basic fundamentals. I was thinking more so for last hitting creeps, jungle clearing efficacy, and proper ganking routes. I would like there to be one for team fight positioning (lord knows I could use this one), but I feel they are too dynamic and chaotic to get an accurate assessment of a players ability to stay safe; while providing meaningful contribution to team fights. Maybe there could be one for efficient ward placement. That might be able to double over into ward negation; however that's also situational.
