FdL when piloted well is arguably the best combat ship in all Elite. FdL piloted badly is one of the most annoying experiences a startup combat pilot can experience in, again, all Elite.
Personally I like it, especially now that we have more options for the class 4 hardpoint than just a PA.
So if you want to try, go ahead. Put some lasers in C2s and something kinetic and hard-hitting in C4, engineer the thrusters, slap a load of shield boosters on her and hooray into battle.

Though be warned, she's unwieldy, drifty and sounds like a wounded gargoyle. It's an... acquired taste.
Otherwise try Mamba. Equally awesome.
