Is the vote kick system improperly implemented for how it's actually being used?

If they don't allow kicks for different play styles I don't think you realize what would happen....you would get punished for removing any player even if one single player was forcing their play style on 3 others who didn't want it.

Forcing people to do something that they don't want to is a kind of harassment. They are not abusing anything in this situation.

In your example, if they ask the tank nicely but he keeps on ignoring them and kept forcing his style. Just kick him for harassment.

In the end, you want people to be more cooperative rather than selfish. This is one of the ways to make sure that players adjust to their party needs.
