Most serious rankers do 5-4 runs for ranks. This requires a lot of bauxite and buckets.

2-3 also helps ranking while helping to farm fuel. Completing daily/weekly missions is also a good way to get ranking points since it is subsidized (probably excluding 3-3/3-4 one). Besides 2-3 you want to run a map that is somewhat easy to get to boss and has HQ xp.

It really depends on how much time you want to spend. Going for top 20 requires playing a lot everyday. Top 100 or 500 tends to be much more manageable, but can still be time consuming depending on server.
