Pushing for Balancing terrain or matching energy against unfair bullies

In my Warhammer club, a small group of players tend to favor vehicle-heavy shooting lists and set up terrain to their advantage—creating large firing lanes with minimal cover. As a result, they win most of their games, and it's reached a point where others don’t really want to play against them.

To level the playing field, I decided to fight fire with fire, running my own vehicle-heavy shooting list and challenging them. I ended up beating them, and now they’re complaining about the lack of terrain—giving them a taste of what most other players experience.

Should I continue matching their energy until they adjust, or should I keep pushing for discussions about terrain balance and why it’s crucial for an enjoyable game for all players? I'd love to hear your thoughts on this.
