Jeez sounds like most strategies involve outside help or borderline "foul-play" (i know others might not think so). As to a closed roster, no outside help war, not soloing (just a straight forward war) what do you think the best strategy is? Depending on how much a l4 lc spy makes per steal compared to a lc warrior, it might work out that assassinates are more advantagous than steals. If a mid level spy can use all pots and comtinuously pin a top player (with others) this would reduce the enemies potential plunder (and yours) but at a net difference that helps your clan. With their top guys hopefully pinned, and kept their by your mid-level or lowbies, ur top players could hit their mid level players. Of course crystals are of concern, but can be remedied by having your spies re-assassinate. It's a general idea which could be adapted to the situation, and is for clans if about equal stats
Bumping this for war strategies when you are outgunned in war, as per the first month the war system was out and anti-mercing solutions were being sought. (NO LOCKED ROSTERS) pardon caps
Bes tactic is to have everyone active in tge first hour of war. Your top members quicky pin the top opposition and easy sailing from there
