Its nothing like lb sh exploits because you can still win if your strategy is good enough. I didnt start using (ps1) to exploit anything but rather to get all my clan involved in wars and not just hfbc tanks. After seeing how effective it was it was only a matter of time untill many others tried to follow suit. I find primals far more challenging and fun. Also they give a much wider variety to what builds and rosters one can use and still win.
