i have no opinion one way or the other
there are other reasons to install a worshipful master than just ritual.
some people will never be good ritualists, but are good leaders.
in my view, it is one more thing for the master to do, one more thing for the GL to do. While I think it is important that something be done to help, it is up to the PM of the lodge to step in if whatever needs to be done. Here in Mass. we have a masters path that all masters MUST attend. It goes over the duties, how to run a business meeting, committees etc. I have seen men that can not put two words together but do some great things for the lodge. Others that can spit out the ritual in their sleep, forward and backwards, but do crap for the lodge. Do lodges in Texas hold a class called the masters path and make the masters go to it? voted unsure on this topic

I don't think GL should make it a requirement to hold a C, B, or A certif.
We also have the L.I.F.E. program for those who cannot get to a Wardens' Retreat. As John & others have posted, the resources are available- it's up to the Brother to avail himself of them.
Yes, some Masons are good ritualists, some are good leaders. To be WM, you should at least have a little of both. At least be able to open and close.
