I'm confused. VT is Voltaic Tempest, yes? What does that have to do with playing a lot of LD? When you say LD Bombing Alternate, do you mean a bomb to us in LD other than VT? Because I'm just confused why you're looking for an LD bomb and complaining about playing LD to get it. And also, VT doesn't require playing LD. It's a boss item, you kill the Roarmulus Twins for the tokens. Then, you have to visit basil in the clockworks and pray he has the recipes you need. or, you go to the Auction House and buy them at a premium from players who have done that, because you can't get Boss Item Recipes in the Hall of Heroes.

Perhaps you are confusing VT with Stagger Storm (SS)? Stagger Storm is indeed a Krogmo item, and you do indeed have to play LD/BN until you get about 300 tokens I think to get all the recipes.

VT is one of the best status bombs in the game, by the way. It's worth the trouble, in my opinion.
