Slave 1 is kinda meh at this point. It taunts but it can't take the damage, and its basic doesn't do a ton of damage. Mass torpedoes is fun, but taking the time to spread target lock on multiple enemies usually isn't worth it. It really only shines when you manage to keep it alive long enough to drop the bomb. Good for a secondary fleet, but it's one I look forward to replacing in my arena bench.
I haven't fought IG2000 or bothered leveling my own yet, but I seem to remember it being kind of unimpressive in its marquee event. Like, decent when partnered with ships that can breach, and pretty poor if not.
HT and XB are a killer combo though.
