You can't? Really, like you honestly can't figure out any way to succeed against that? :lol:
Many ways, it's just as easy as outsmarting a dodge/split defender... just takes a bit of coordination, knowledge, skill, timing, and for me personally, charm and good looks :icon_cool: lol
If the guy next to the stacked one is easier, then anyone smart would go for that. If I can get 200 villages instead of 50 from my enemies, then I'll chose 200. I'll grow and keep doing so, by me growing at a higher speed it'll allow me to overwhelm my targets. In TSE we're growing, we take villages fromsuitable areas to gain in. We aren't dumb enough to attack the enemies most skilled and stacked target, when we can do so much more.
Unless it's a very good reason to target the most skilled and stacked player, I wont do it. As I say, 200 villages will allow me to do much more than 50. At one point when the more skilled players lack supporters, then you take them out. But of course you can always play smart, Lrdconquer and lord ace tried to, they gave me red reports on two villages. No matter the skill or activity they had, they wouldn't get through my stacking. Unless they would overwhelm me which we recently did with PKs. However we aren't dumb enough to target single players, we target entire areas.
As I said, unless it's a very good reason to attack the one you barely can get through the stacking at. Then hit the easier one and outgrow the enemy.
Tennis, with your last statement it sounds as you're new in TW. Please take the first ticket to Benx and have another try.

It's possible to scout and speednoble him. But it'll be harder to both keep the villages and defend them. Not to mention, if you attack the enemy, then an active will try to counter you. As Benx was hard and larger in the area, I went to the DL front. I consider it to have been one of my more successful moves. I just had 995 conquers against lfkd/Sciros after all. That or a few villages from Benx, or rather a stalemate.
Any good enemy goes for the easy targets which allows them to outgrow the next one. Benx did so as well. It's easy to understand that if you don't have nukes to clear a stacked village, then take another.
