in the only clan war our plan played in fh2 we dint have much of a plan or even experienced players.
but the players knew the game mechanics.
this was shortly after 2.0 release
we played 8vs8 on supercharge 32
now since 1 guy never really played the game he just was scouting.
using scout kit + binocs and called in all enemy tank movement via minimap (and of course team speak too)
this way our team had the like an intelligent "wallhack" enabling us to outflank enemy tanks with ease and stop infantry assaults in their tracks.
spotting is important
but dont spam it
