Is two-rounded base in Town hall 10 still hot or not?

As you know that months ago, two-rounded base Town hall 10 is known as big barriers for attackers who want to have 2 star in Clash of Clans War. There are some concepts like below:

There are some benefits of this base:
1) It is hard to call all castle clan troops (in case there are several archers, wizards...), because in two-rounded base, castle clan is in the center.
2) The strongest defense focusing on the center and every def around to safeguard the center.
3) It is hard to use archers and minion in edges of the base to increase percentage, then maybe Town hall is destroyed but the opponent can not have 2 stars easily.
4) When attacking this base, if attackers do not know pincer war attack, his troops will lose their way and move around the base, not enter the center.

Then how to take 2 star of two rounded base in Town hall 10? It is quite easy if you use pincer strategy with 3-4 jump spells and 3-4  golems combined.

Pincer strategy is very effective to two-rounded base

Or even, with the apprearing of witches level 3 and Grand Warden, this base is easily cleared. You can see more strategy with Queen Walk and 9 witches

So someone will questions that should I still use this base or not? Personally, I think you should use two-rounded base flexbile like this:

1) Set it to your farming base, it will help you save resources quite good
2) In a soft war with few town hall 10, you can use this base
3) In a hard war with a lot of town hall 10 or town hall 11, and profile of opponent is 3 star warrior, you should change the base in preparation time.

I hope this share is useful for you guys!
