then thats not downing your self thats just killing your self and that wouldnt fix the problem they would just bum rush the heli and if they down him then he runs off and does that.
theres still a loop hole what then? Remove the option all together at the end game? do you have any idea how big of a nerf that would be too the Predator?
and lastly its not that big of a deal as you can always start the heli and then move away form it keep a middle ground between the heli and the safe zone what can he do then? move back? then he made a safe zone right next to the heli.
