Well... ODA is not a goal but should be the result of intelligently usage of y our army... Having troops is one thing, but knowing how to use it is another... How many world did I see with players having full farms of offensive troops and not using any.. claiming barbs and such..
Although using prematurly your troops is not good neither.. you better grow till few hundred axes before swinging... will be much more useful.. its all a matter of which neighbors you have or how many farms you need to build yourself...
Considering I am going from #1 to #2 spot for sure I did have to clear my area from possible incommings.. It had 2 useful purposes :
1- Clear potential threats
2- Create new farms as my amount of troops is getting higher, I can do more farming...
I don't see a top player surviving nicely on the long term without having the ODA that comes with it at some point..
And to answer another point someone brought up... Of course it is hard to be in top 20 without any troops... farming is a too huge advantage in a ratio 1 world. Although not everyone in top 20 have the same amount of troops and prolly many other players between rank 21 and 1000 have more troops than some in Top 20
Its for you to risk hitting them and finding out
