Honestly speaking, I have the lowest ping of 170 and my ping average is 220 so If I say ping limit should be 300 then I am only being selfish here, so are the guys above me who think 100 or 150 should be limit. There are regular and very good players from countries which are far from the location of the server and they have 350 as the lowest possible ping and so its unfair for them, I would still suggest 400 as the lowest ping as playing or fighting someone beyond 400 is just not fair on both sides.
