Those born in Capricorn and Taurus dislike this sign's unpredictability, which they see as flimsy. Scorpio may also have a natural aversion to Gemini due to their compatibility.
Cancer needs to feel needed, and Gemini, Sagittarius, and Leo can't provide that.
It's possible that Leo will find the rigidity of the signs of Capricorn, Taurus, and Virgo to be too much for him. A lot of earth signs think Leos should just get over their own egotism.

Virgo and Capricorn usually don't have the initial spark that Libra craves, and that's a problem.
Aquarius can be too intellectual for Scorpio, just like the head and the heart don't always agree. Scorpio should avoid pairings with Leo and Aries as well.

Capricorn is viewed by Leo, Gemini, and Sagittarius as being too serious and stodgy.
Aquarius, with its preference for logic and openness, may find Scorpio's way of thinking difficult to understand.
