I sucked at PK for a long time, I practiced and got better. So can people with role writing. I've seen ESL people make immense strides in their role chapters as characters have progressed and I don't think rewarding role writing is in anyway a detriment to people who may not be the best writers.

You can always write point-form roles, several smaller entries etc. You will get to 1400 in a reasonable time frame. This in no way favors strong writers only and honestly, many times a lengthy, rambling role can become dull and a burden.

In fact I am certain some recent RC winners were ESL people who worked at it and constructed a good view of their characters over time. I 100% agree with you that Equality of Opportunity is extremely important.
