It's not worthless, depending on the regional. However, when I was applying around, nobody would touch me unless I met the FW requirements, which in most cases were 1000TT/100MEFW.

The few that I know of who are restrictive are ExpressJet (don't count it at all) and SkyWest (2 helo for 1 FW hour up to max of 500 helo = 250 FW). Of course those two are probably the most desirable regionals nowadays, so take that for what it's worth.
