have noticed fewer isles with double walls. Has anyone analyzed the benefits/strengths vs. cost of these defenses? Is it better to double or upgrade a wall?
Doubling adds, well double the hit points. Upgrades become incremental bumps, only 250 up each for the last two level 8 and 9 walls. BUT... A dying bomber blast will damage both walls if no space between. Prob should have one space between to avoid this OR give in to the double fence rectangle everyone uses at higher ranks.
I think you will have to think of where to place your defences with the use of double walls. Double walls are not effective against the gunners range, it would be better to keep a gap between them.
Or move the defense back one space, but I agree, a space between the walls does work better vs: bombers.
i need space for just a couple more walls, so hard to get everything to fit as planned, double wall, or spaces. (I do a mix).
