federation t3 ships need to be balanced if anything they are useless ships
That’s funny. Their frigates as as faster than Empire and Jericho fighters, their fighters are faster than Empire and Jericho interceptors, and their interceptors are faster than everything. Compare the tank of a Fed guard to the tank of an Empire or Jericho R9. Don’t treat their frigates as frigates and you’ll be fine.
Anyway, back to the OP. Static barrier’s only about self preservation really, except against singularity. Because of singularity, which seems to have been nerfed enough in PvP, static barrier’s almost useless. Warp gate’s bugged in my opinion since you don’t follow the engineer’s route. I generally ignore any I don’t create. You can make the same warpgate claim for an LRF because it needs to get into position swiftly to be effective. At the same time, those are both modules that engineer something and should fit on an engineer. Having all the guard modules being timed I don’t completely like, mainly missile shield. Missile shield helped the whole team and not just the guard.
Guards are situational, they’re better for DSR than capturing beacons, but both are part of the balance for a win. If I fly a guard, I’m probably not going to capture any beacons because the interceptors got there first. I could survive and get kills so my DSR could go up easier. A frigfest in beacon hunt will probably lose against an all interceptor team.
