I disagree. If you go deep and get sneezed at, you die for it. Smart players will make sure Luigi stays off the stage once everyone starts to learn how characters function.Luigi has a pretty nice off stage game too so don't be afraid to go for some deep gimps
The most I've ever gone offstage for is dthrow followups (either starting one or continuing one such as triple fair), attempt to catch people with a dair spike, and the occasional cyclone spike attempt. I'd change that "deep gimps" to more of a "has great edgeguarding tools" because Luigi should really be staying close to the stage due to his poor recovery. I guess you can go for vertical deep gimps since his vertical recovery is acceptable but even then you better know what you're doing.
With customs legal though you can go as deep as your heart wishes for a gimp.
