A suggestion: Only 3 squads can retreat at the same time to a FRP so that blobbers only retreat a part of their troops to an FRP and the rest runs back to the base (and gamble that their best troops will end at the base). It punnishes the blobber but doens't go harsh on people that play across the whole map and retreat in diffrent instances.
The only problem I tend to have is that it shoots outside of it's given range (the green dotted circle). Which can be extremely frustrating when trying to walk around it. For the rest, do the things the other commenters are saying and you should be all right.
