With the training system as it is, we will always have to field a flawed team, the "complete" player can't be built, unless you are playing in a low division where an all-around "10" is more than sufficient to bully the other players. Maybe it's just because we still have not figured out how tactics really work - maybe we never will, because the formulas and variable are just too difficult to figure out.
In comparison the the real world: you won't be able to find the complete package there either. The top guys are all weak in some aspect of the game, so building a team to cater the strenghts of those players seems logic. Some teams will forever be chucking threes, other will try to outrun the competition and other will have their own bag of tricks.
If I was you, I really would not care about the B3/NT competition, where LI might still be a problem. I run almost every tactic and most of the time I am happy with the result.
