The Raiders do have to bring more fighters and can do so at the same cost - 1 Patrol Point buys 8 Delta V's. They also get a Skirmish level fleet carrier.
What the Raiders don't have is powerful heavy ships. Their capital ships appear to be relatively tough, poorly armed and well supplied with cheap fighters. The whole fleet seems geared to support those fighters and will not do well against the heavy ships of most other fleets.
So don't play them as a battle fleet, play them as Raiders. They're pirates, so give them some civilians to attack. That means something like Convoy Duty or one of the Raiders scenarios in various issues of S&P. Used in that manner, I suspect the Raiders ships are balanced for their PL's.
Back on the theme of win vs. fun, I wouldn't go as far as the suggestion in S&P 46 to refuse to play against anything other than civilians. But, if the other player is using Raiders, I would also not demand to play scenarios like Annihilation. Rather I'd want to play something more suitable, e.g. Convoy Duty at Raid level or lower.
