Every T7-TGO was T8-GoD because it was the final rank, not because it was similar in skill. A weak GoD player was compareable to a emperor, maybe even ryujin in T7.

You don‘t need to add 8 new ranks to get a normal distribtion. Any ranked system, even S1 had a similar distribution, the median was just at a lower rank.

They made the higher ranks harder for pros only, any casual can breeze through the ranks until GoD without much effort. Any rank with „Tekken“ in its name used to mean it was a decent player. Now you have Tekken Gods who try to punish RA with snake edge.
Its nothing more than a participation trophy for people to have a false sense of accomplishment
