Only lvl 10 so can't pick it up yet, but have been matched against quit a few. They look really cool and fun to use, from what I've seen people have been uses it as a harasser and flanking ship, shooting in for a ram on anyone who extends too much or isn't paying attention. This is exactly how I try to play one of my Gora/Heavy/destroyer but as you can guess even with warp jump and scrambler this isn't a very effective yet still fun tactic.
How is the light destroyer?
"I haven't lost an arm, brother. It's right over there."
Well, you trade armor for speed, and that's pretty much all there is to it. You'll certainly have an easier time ramming than with a Gora, on the other hand you can also be killed very easily.
Get an Athos at level 15 first and train your ramming with that, it's not as fast but much more forgiving, plus the guns have better range.
