There are heroes in every role that are easier to use than others. If you just started playing Mobile Legends, I highly recommend you to play heroes that are easy to maneuver so that you'll have a grasp on the basics of each role first.
There are Marksmen that deal significant damage even in early games, such as Brody. However, it should be noted that the majority of Marksman heroes in Mobile Legends are the main damage dealers during the late game.
The most important thing to note when playing Marksman is to prioritize buying ITEMS. And for you to be able to buy items, you need a lot of gold (the money used in Mobile Legends to buy items).
Now that you are already aware of the key things you should note when playing this role, let us now proceed with the list of best Marksman heroes for beginners.
Layla
Who doesn't know this hero? Layla is the first hero players use during the tutorial parts of the game, and arguably, there's a reason why. Layla's skills are beginner friendly because they are straightforward and simple.
She uses a gun to inflict damage to enemy heroes, minions, and etc. Her first, second and Ultimate Skill fires different Malefic Energy in different forms. However, since she has no mobility skills, I highly recommend using Spells such as Flicker, Sprint or Purify so you have higher chances of surviving when the enemy team ganks you.
Remember, you should build items with high Crit Chance when using this hero, such as Windtalker, Scarlet Phantom and Berserker's Fury. Having items which will significantly increase your basic attacks are also highly recommended.You can also buy items with Life Steal capabilities with this hero, such as Haas's Claw.
Miya
Miya is one of the popular Marksman heroes being used in both low and high ranks. Unlike Layla, this Marksman hero has a skill that you can use to chase or escape from the enemy team, which is her Ultimate Skill.
I am putting emphasis on the mobility capabilities of Marksman heroes because experienced players would likely target them alongside Mages. They will find a way to stop you from farming gold so that you can't buy your items. As previously mentioned, most Marksmen, including Miya, are pretty strong during late game, considering they have the correct build.
Buying items with high Crit Chance and additional attack speed is highly recommended to this hero. You can also buy items with Life Steal capabilities with this hero.
Lesley
What I like about this hero is that she has a skill that enhances her mobility, and it has a short cool down.
Aside from her mobility capabilities, her Ultimate Skill is pretty useful in finding enemy heroes who are hiding in the bush. It is worth noting that when a hero hides in bushes, the enemy team will not see them. Bushes are perfect for ambush.
As for her build, items with high Physical damage, Crit Chance and additional attack speed are recommended.
