Kayle is mostly a dps in my point of vie because of her third move, Righteous Fury. That move is very useful because it turns Kayle attack type into range instead of melee for a short amount of time. A really good combo is first attack the enemy with Reckoning, then use Righteous Fury and keep hitting him from far distance, finally if you get gganked while using this use Intervention so your invurnable for a short amount of time and run to the turret. This is one of many combos I use in battle. So I hope this information helped you.
