Flags gives only more chance for win but it's all about skill. If you are talking about "one-side flags" marketplace has it too. If your team will group up under the flag on left site to town hall, enemy don't have chance to get there before flags will hang up. Of course, trenches have 2 flags like this, but I'm just saying that there is no map without "one-side flags". Anyway it's your league, your rules, do as u wish. This mod may be for me but I don't see need for it.
BTW. Jubeg, don't double posting.
