It's the most competitive if your local meta is a Slaanesh meta. If It isn't I recommend a heavy grot list but you could try to improve the lista with rockgut troggoths/Dankhold, some boingrots, more fanatics and/or Skagrott. When the fanatics get the points drop, they'll be a must...
Remember, your objective is capture the objectives, you don't want to fight a lot of combats.
