Hey,
the past few days I had a lot of fun by just grouping up with others, stay together and just walk one way all with passive radar. Once we make contact we concentrate fire on a single mech which will die fast.
Fun all the way... but it has one big downside: The other team usually rage quits instead of grouping themselfs.
So guys, if you get blasted away over and over again, stop lonewolfing.
There are two sentences needed for victory:
Stick together!
Meet and XY (coordinates) and go passive.
