This is possibly worthwhile for any newbie to intermediate. In AW, stacks dominate and rule without any doubt in my mind. One month ago, I was facing easier matches but as things progress, my matches have gotten harder. Last war, i realised that there was no way I could compete at this level without some serious rethinking.
Firstly, I realised that all i have to do is defeat my opponent 3.x times (if possible). That gives me some real flexibility given my limited roster. Last war, my opponent was a R, P, R, G, B setup; Sumitomo +19, Cyprian +19, Ares (tank), Kashhrek (+ fast mana troop) and Kiril +18 (3864 tp). I figured I could do it once, maybe twice? Clearly some different thinking was required! I came up with 4 x 3, 2 stacks: Blue, Yellow, Purple and Red.
1 (Blue). Strong against tank, weak against one flank and neutral to others (without regard to colour stacking).
2 (Yellow). Strong against Cyprian wing and neutral to others (no dispel).
3 (Purple). Weak against Cyprian and neutral to others (+ dispel).
4 (Red). Strong against Kash, neutral against others (ALARM. NO dispel!!!).
Attack # 1 (3, 2; 3B,2P) defeats superior (by ~300 tp) without breaking a sweat (3573 defeats 3864).
Attack # 2 (3, 1, 1; 3Y, R, G). Again! (3636 defeats 3864)
Attack #3 (4, 1; 4R, G) Total defeat!!! (3365 just totally fails ~ 14% of available points) That was just tragic.
Attack #4 (3, 2; 3P, 2B). (3111 defeats 3864) Clean kill!
Attack #5 (2, 2, 1; 2P, 2 B & G). Fail, but secured points that guarantee alliance victory!!! (33% of available ponts for that alliance member).
