@veteranashe Seton's was my favorite map, and some time ago I developed a tactics which allowed to achieve 8 win streak on Seton's. I like to develop tactics, yes : )
If it will be interesting for people, I will make a post about Seton's too. But this is quite similar to this, with some modifications related to islands.
Actually on Seton's it works even better due large distance between bases, so allied forces can't help quickly when coordinated attack is started. I didn't excepted that it will work on Dual Gap where distance between bases so short, but it works. At least on low-mid ranks, Don't know yet how it will work with 1500+.
Dual Gap I always found too boring due its bias towards game-enders and long turtle game-play. Still better than Astro Craters anyway : ) Don't get me wrong, battles on these maps always large and epic. Just seems too straightforward sometimes.
But I noticed that Dual Gap is very popular, seems like even more popular than Seton's, so I decided to try to develop something unusual for it. Also it was interesting to answer a question "Is there a tactics which allows solo player make a significant impact in 6x6 game".
