I have a feeling that the items are going to be seeing some sort of change in the next patch, even if it means mixing them up differently to better avoid those frequent combo Trollteor outcomes.

The luck thing though is kinda just what it is lol. The fact any beneficial item appears is purely luck, and that's perfectly fine to go with. If it weren't, I think a game like Mario Kart would see complaints about the random item distribution. Even moreso for FFXIV to be okay, due to the fact racing isn't the point of the games existence, so it's not going to be as intricate as MK. There were several races that I took part in where everyone getting hit by the Meteors actually helped me win 1st more often than them causing something bad to happen.
