Maxed out skellys and mortars two weeks after they came out, halloween update, I was maxed until they added them, cut into my wall upgrade effort. Next war, prep day tomorrow, I will take pics of placement and the loot available on war day, provided we both get attacked and by the same level player, since that seems to make a difference, I will post them along with our profile pics so you can see the difference in our bases and troops/hero's (we are both max def now, he just caught up). I have seen several bases ranked lower with more loot available, ya it threw me at first, but after several wars I just said, huh...oh well. Map placement does not seem to have an effect on war loot IMO. I normally see this on rushed bases where a TH9 is lopped in with TH8's or a TH10 mixed with TH9's. King is also stronger in our clan other than walls. The loot difference would explain why the top guy always attacks me first from the enemy clan....
You can look at our bases Clan- Agentofdarkness #92YV8PCR My ign - chrism clanmate - nate
