#2 Leg-side wides

Apart from the introduction of free hits, Test cricket can opt to include wide balls going down the leg side. In limited-overs cricket, the margin of error for the bowler is very low. Any ball which goes down the leg-side or even slightly to the right side of the leg stump, a wide ball is called. There have been several bowlers who have even targeted batsmen with short pitch bowling trying to bowl down the leg side. 

#3 Having a reserve day for rain

Earlier this year, the first two Tests which India played in England this year vouches for this change in the rule. With no reserve day, India would feel that they were robbed of a win while fans were robbed of what could have been an incredible finish to a good Test match. If the forecast predicts that an entire day will be lost or a significant chunk of overs will be lost, a reserve day can be added to a Test match.
