I disagree. In that case with peekers advantage as he was hiding, he wouldn't even been able to react to you before you had landed. It wouldn't have changed anything if you only ran or if you ran in jumping in that case. Either remove 3.3 or enforce it. Jumping in combat to be a target...
The only people who bhops with a gun are shotgun cops. They only have to hit 1 shot on you, and you MUST hit a headshot on them in order not to die. Saying that all you have to do is cripple them is stupid, it doesn't matter if you cripple them as they are already a few meters apart from you...
