Rangers are a great class for beginning players. They get their meelee skills earlier than other hyrbids. Paladins and shadowknights do not get dodge until level 10 where rangers gain it at level 8. While all hybrids gain double attack at level 20 only rangers get the ability to duel wield and they get it at level 17. Each hybrid gains a special skill.
Paladins can lay hands once per day and shadowknights can harm touch once per day.
These abilities are special abilities that only those two classes have. They also are the masters of this skill and have the largest range on it. This skill can be incredibly useful in outdoor zones. There are certain monsters in your level range and you might wander around for 5-10 minutes looking for a skunk for example as it is a level 2 monster. With tracking you can simply track it down and move on to the next one.
