Can undo a lot of poke, and give her carry a vital boost of movement speed to dodge incoming skillshots, especially from champions having crowd control.
Once she gets her Ultimate R, she can pretty much keep any form of engage away from her carry as long as she has her Ultimate R up.
She can use her W to dismount and body block vital skill shots for her carry. Besides, her E can heal for more damage when her carry is low on health.
Can be killed almost immediately if she is caught out of range from any of her allies. Same applies if her W is on cooldown.
Her E costs a lot of mana so she is very susceptible to poke damage. Once out of mana, she can’t really do a lot in the lane.
Very susceptible to all-ins when her Ultimate R is down. A crowd control chain at this point is enough to kill her carry in the lane, or any carry which is isolated.

During the laning phase, focus on poking the enemy down to gain a health advantage. When the enemy is low, commit to an all-in.
Try your hardest to keep your ADC alive for as long as possible in lane. Provide them with heals E whenever they need them.
After destroying the bottom lane tower, rotate to the mid lane and try to take that tower. This will open up the map and give your team a gold lead.

As a Support, you’re quite vulnerable and can easily be killed when going to ward, when you’re moving around the map, and when you’re alone. To reduce the chances of dying and getting caught out of position, try and stick with your team at all times.
Keep a constant eye on what major objective is spawning next. If it’s spawning soon, make sure you place vision around the objective as quickly and as safely as possible before retreating to safety. Having vision around major objectives is key.
Look for picks during the mid-game. If you can pick someone off with the help from your allies, you can abuse their death timer to earn more gold and possibly take a tower, an objective or get more kills.
Ward major objectives and place vision in high traffic areas in the late stages of the game. Keep them warded so you can see the enemy move around the map and see them starting the objective.
Stay with your team at all times. Avoid moving around the map alone so you do not get caught out. Getting caught out will result in your team having to play 4v5. Do not ward alone unless you know where the enemy is.
Peel for your allies as much as possible. Keeping them alive for as long as possible in team fights is a must in order to win the game.
