You fellows pain me.
The reason most people think High-Rate is dumb is because they are looking at it in comparison to Low rate with its base level of 99, job 70, etc.
Consider highrates as an entirely new experience seperate (because in truth, they are) from the mechanics of low rate RO. It has its own potential for balance and can be just as great as any low rate. I could spend a long time talking about this, but i think you get the idea.
Conclusion: highrates and lowrates are like the difference between skate boarding and sail boating. One is more smooth and pleasurable, while the other is bone-crushingly fun. Both are nice, which is why both high rates and low rates still exist.
