i dont know if it was because of last hitting or creep block or just newer releases /reworks
but many old champions had and still have 125 range
while new ones mostly have 175 as melee or irelia 200 as melee
i think older should have a look over and be updated to be added to this ever evolving game and be 2019+ not 2012
I think juggernauts and lane bullies should have 125 range and that the range of melee characters should increase up to 175 based on how submissive a champion is. Tanks in general(because there are lane bully tanks like Naut) would be at the higher end and bruisers likely in the middle at 150. The idea is for farming in the top lane to not be as onesided and for melee vs melee to not be so threatening. AP melee champions would have 200 range. Of course champions would need to have their stats adjusted for this to happen without breaking things though.
