purples are sufficient in blocking max wb (just barely but when they spam all them at once still take 2 as lvl 10) thus making the the most efficient wall upgrade for price-effectiveness ratio, considering most ppl use hogs and lalloon to get 3 stars idc that much about walls, ill use my excess elixir and half gold to double upgrade them while keeping my defenses going
there are rules to rushing, not like i will tell any of you because you won't listen
if the troops work fine for me and your's suck then you're the one who sux
I've done all Legos and started lava ( only done about 15) but when the earthquake spell came out I stopped focusing on them so much. If I have a shed load of loot and days until a builder is free I will dump on a lava but for me there are too many ways around walls.
Your defences and base layout is what will prevent others from farming you. Wall level doesn't make a massive difference in war apart from to add you your wieght in matchmaking.
Finish the 9 and stop if you war. Seems as if lava walls are on par with upgrading xbows in terms of war search difficulty. It will totally mess with your entire clan during war search.
