When i play doubles, usually i pick a continent to hold and my partner picks a seperate one and then we work together with our added bonuses to attack the enemy. This has worked pretty well - were undefeated in a doubles tourney so far- but recently i've come across another strategy where a team doesn't worry about bonuses in the beginning and stacks both player's armies onto one spot, and then attacks into a territory once either me or my teammate establish control over that.
Which is a better tactic, and how exactly do you utilize the second tactic to be a effective one?
any information would be wonderful.
