@ITD Only the fact that you've used gowiwi as a TH 8 is incredible by itself lol. Nice job!
I remember we warred against you guys, but don't remember any of the battles. Was I using this layout or testing another one?

@xindc This anti-hog-ish base had already given some gowipe attackers hard time, due to it's 4 teslas surrounding the TH. I wanted to also have a good gowiwi defense, but didn't have success, even being a maxed out TH 9 with almost all walls at level 9 and heroes in their early teens. Well, I'll continue trying if I find the time (I'm recently quite busy irl)- according to my rough estimates, I'll be at TH 9 for about one more year, working on fully maxing it. :)
At the time I was testing the anti-gowi*, a clan mate of mine (another high level TH 9) was using this^ design, and after the release of the fourth mortar, he's fairing pretty well in wars recently, often being only 1-starred at the end of our wars.
What does for sure work on preventing 3-starring from a gowi* army at TH 9 is to have your defenses upgraded, the most important (if not all) walls at least at level 9 (your attacker has to use their jump spell to enter your core, rather than to exit it) and a fairly compact layout with many compartments (most of these widespread layouts, where you don't need to break a wall to enter the first layer of the base, are not at all good against gowi*).

@xindc to be honest I'm not satisfied with the latest results of the anti-gowi* and have ran out of ideas of how to improve it more. Thus I'm leaving the project for now and will try to create another one. :(

crystal 2/3*

Yep, ninjaboyjeff, I'm using it for farming just like you described, just also surrounded the DE storage with small bombs and moved the black air mines into the outer layer so to work against healers. Moved the TH in a corner totally unprotected and I'm barely getting anything other snipes in crystal 1/2 (recently don't have gold/elx to offer to an attacker though, but my DE available to steal is quite often at max- 2500). :)

Hi xindc. I've also noticed the issues in the anti-hog ring, but in my cases the hogs were separating into 2 groups, which is not that bad. I haven't been attacked by dragons with this setup- I had nearly maxed defenses while using it wars. Another clan mate who uses it now and has maxed out defenses doesn't get attacked by dragons as well.
As for my new anti gowi* base- only 6 attacks on it so far and I've tweaked it a little after almost every one of them. Results so far are: 1*3 stars (by a skilled th 9 gowipe loons), 2* 2 stars (th 10 hogs and a new th 10 gowipe), 2*1 star (a new th 10 gowipe and a th 10 hog attack) and 1 successful defense against some not-so-skilled th 9 balloonions. A major tweak came after the 3-star defense and now it's performing much better, still feel it needs some tweaks before it gets posted publicly.

@M150 Bad to hear it. No idea what army you've been attacked by, but I must admit that the base is quite so weak against gowiwi.
@clashextreme With my previous build, where the mines were in the second layer, I was 2-starred by mass dragons in wars a couple of times. The problem was that since they were attacking me from one of the sides, they did only activate one of the black mines on their way to the TH, which wasn't enough to prevent the 2 stars. Thus I decided to surround my TH by air mines, hoping that this way I'll be able to kill the couple of drags that are aiming for my TH (I'm OK to be 1-starred by drags, who wouldn't be?). Ever since I changed though, I haven't been attacked by air. Rather I was 3-starred by gowiwi a couple of times, so now I'm testing an anti-gowi* base now in wars, that I haven't made public yet.
Cheers, Mimo :)

@doberman74 Yep, every base has its weak points. :)

Update: rearranged the core and closed the compartments containing double giant bombs. Think it should have became more anti-drag. :)

Thanks Aharon, JESTSTAR and the nameless guy! :)

Yes, I'm pretty much aware of that. Still prefer having a centralized TH.
