its a legitimate stratigy but weather it is effective is another thing. With careful planning massing can easily be defended against. massing is most effecteive later on when armies are reaching their limits, there are large numbers of covert units and untrained units have run out. When I was massed at the end of last round it was having large impacts, only thing that stopped it being an issue was rasta and JDS quitting meaning that 2nd place was too far behind to benifit. Im back on top again now but i made an error in judgement earlier on and followed a route of devolpment that allowed falco to gain a larger advantage then I had origionally anticipated which is why it has taken so long for me to get back to #1
