Simple question, don't you think it's little OP?
Personally, no.
The worst is OKW vs USF when USF player went for Lieutenant. Even with dropped AT gun with Airborne, Luchs can just wipe everything cause of pudding Rifle AT nades.
That's possibly a fair point Australian, but shouldn't you sort of anticipate the Luchs? After all, it takes a fair bit of building to get there and there is plenty of time to plan a counter. The big fuckoff gun truck is a clue, for starters. Even with Lt. you can dump a utility car mine *and* have an early zook.
When compared to Stuart or T70, Luchs is deadly for infantry.
That is it's primary and possibly only role. I made one last night in a 4 v 4 and came face-to-face with a T34. You can imagine how that ended.
Luchs is very low risk unit and really, really high reward.
I have to take you back to my earlier point - look at the fuel cost and building commitment to get the Luchs - you are forsaking a lot of other stuff. It's medium risk / high reward. So maybe a tiny nerf to ROF perhaps but even that I'm leery about.
I'm also not convinced when points are illustrated by showing videos of elite players. 90% of us don't play at that level and never will. Elite players are *meant* to do crazy cool things with units, it's what they do. Too much of this game is already balanced for 2% of players who think they should call the shots.
