Here is an interesting anti-wb design.
Here is my views on how the wall breaker will react if they are placed directly ON the position of the town hall( for easier referencing)
Assuming same deployment point.
Assuming that the tesla is already active due to nearby troops.
Important note that the town hall is bias towards the left side.
1)they will target the edge of the left compartment that the tesla is in as it is the closest due to that additional "edge" poking out.
2) then they will target the compartment that the wizard tower is in. But not at the T junction
3) after the tesla and wiz twr compartment is blast open, it will then aim at the T junction that encloses the active archer tower
4) after that it might target the cannon's compartment due to it being relative closer than 2nd layer
5) at this point, the wb will definitely target the 2nd layer of wall after the tesla, wiz twr, archer tower, cannon's compartment are gone.
BUTTT, that will be the case, assuming you attack this base head on.
IF you attack from the top left tesla corner, it will blast the start of the tesla compartment, then blast the T junction of the wizard tower, after which it will proceed into the 2nd layer
Need.. Picture.. Cant.. Visialise.. :P
