Hmmm. I'll do a review of the top 10. Hopefully this doesn't sound bias. Also, any data included in this post is based on this context:
1. Farmercy
780 total villages
280 Internals
137 Barbs
However, there have been 62 caps against Ninja.
Only #9 for ODA, could be higher, however, they farm a lot, so that could be where the offense is going. #141 for ODD, and #31 for ODT.
Overall, I think the account will do well. If Farmercy focused soley on hitting turtles, I think turtle could be hurting.

Lots of internals as well as barbs.
I normally make around 6 posts per game world, so here is my first for World 72.
This is not a bad way to assess players, but I think you need to differentiate between barbs relating to ex-players from <=3K barb farms. Until about a week ago, I had only around 30 conquers on 3.5K barbs. I am taking a few more now, given everyone else is doing it but there are several players that over 1/4 of their villages were farms that dont fight back.
Also, although this is difficult given co-plays and people creating new accounts, previous world performance is relevant.
From my own perspective, I finished Number 1 in World 48 and was Duke of the winning tribe. I would argue that this does indicate that I might be at least a semi-decent player, especially as I did this without a co-player. Getting to the number 1 position in two worlds is very unlikely to be a coincidence.
Achievements are also another valid dimension. The best players can attack/defend and also are good team players so there are a number of achievements that help you determine what type of player they are.
Of course, ODA is important. However, just because you are not at the top of the ODA charts doesn't mean you aren't aggressive. Mindlessly throwing nukes at obvious stacks gets you ODA but doesn't win you many villages. The cleverer player will noble the villages that are supporting the stack and kill the troops (I have often thought that this should count towards ODA, or at least be recorded, because you do essentially kill the troops outside of the village when you noble it).
Internals and barbs (both high and low points) are part of the game and just because you noble this way doesn't make you a bad player, as long as that isn't all you do.
Of course, the way this normally works is people you like are good and those you don't are bad and I guess that will likely never change.

...however, the clever get someone in the tribe to sit them and then it becomes their fault!"
