I have to admit that I am not surprised by your opinions, because I agree with you . Nevertheless I have also to confess (based on my own experience) that tank color coordination could be a very effective tactic. I think (remember: it’s a pure speculation, without any proof) it depends on two things:
- the boards (just as @Duaneski said)
- the powerlevel.
If I remember correctly, some time ago our alliance many times had a hard time against alliances with all the tanks in the same color. But it was the age, when most of us had one, maybe two rainbow 4* teams. As I believe, our alliance is pretty good at wars, so most of the time our opponents are much stronger than us (at least on paper). Therefore we had to face 4*, sometimes 5* tanks. After the first, or second wave of attacks we had to deal with then using our 3* and it was really hard, when all tanks were coordinated.
Right now, when we have five, six, or seven full developed rainbow 4* and 5* teams, the problem doesn’t exist anymore. As one of my fellows said, we didn’t see any significant difference in a war against coordinated tanks or not. Just like @MidnightOil said, as long as the board isn’t mediocre, I don’t need to stack strong color. With the neutral or, even better, fine board, I can take what’s mine even with the neutral color.
So, considering the fact that out opponents are usually stronger than us and they also have deep rosters, tank color coordination isn’t so important anymore, and the better idea would be just to field the best defense teams we can.
Does what I say have any sense, or am I just babbling?
