Gonna post a real simple, basic truth about this game:
Flying your list well is the mark of a good player, reacting to your opponents list is the mark of a great one.
Whisper, Echo, Fat Turrets and, soon, AT Interceptors and ATC Vader, are not game breaking, you are just not that good (this is a hard pill to swallow I know). React to your opponents list. Flying a 3/4 X-wing list against a phantom? Give up loser! You can't get a well flown Phantom in arc! Bullcrap. Wedge kills phantoms dead, fly slow, hug the edge widen your arcs, it's difficult, not impossible. Please stop saying a ship is OP because it beat your one-note, jousting-based, "strategy".
I took a Whisper/Chippy build to my first tournament having only played with Whisper once before, placed 8 out of 18, would've done better had my Whisper not been one-shotted at range 3 early in the last round. But Whisper is invincible OP! You must just suck. Or maybe my opponent was just better than me? Buzzsaw Whisper is easy mode, easy to fly, easy to kill.
Stop demanding nerfs and adapt, seriously, these forums are becoming a real drag.
