Probability of success and merit are different things.

For instance if you know for a fact that you have been fired due to your race (perhaps you were outright told this is the case), but have no evidence (you weren't recording and there were no witnesses), your case has merit (it really did happen), but unless you get lucky and some evidence appears in discovery your odds of success are miniscule.

I'd argue that in such a case preventing such a person from seeking justice would be wrong, since they were really victims and diserve redress.
