I'm assuming the total revenue for the lawyer should be similar to what they'd get in a class-action, assuming they actually gather a critical mass (for either case); and then if they treat it as a class-action, where most evidence is somewhat shared... then you could re-enact the scenario

Whats not clear to me is whether a class-action must be treated differently from 300 independent lawsuits, assuming a single lawyer/group handles all the cases, from the perspective of the lawyers. Ignoring I guess the cost of 300 independent filings, but I'm also assuming thats a rather small part of the overall cost.
