I am reposting here because I want to discuss something a bit more that really received no attention from content creators or anyone really which is one of the hugest changes in patch 2.4.
Left click, right click, and quick casting melee abilities (and other abilities) are receiving a significant improvement in patch 2.4.
Before, when you right clicked a target and held your mouse, you attacked it till it died and then you wouldn't acquire new targets unless you released and re-pressed your right click. You could right click the ground, and then you started attacking targets or moving, and you would acquire new targets even if your current target dies, and you could just hold it down. But the thing is that you'd have to make a conscious decision to click the ground and not an enemy specifically to know that holding the button down would continue acquiring new targets.
In 2.4, if you right click, behavior will always be the same - you will always attack and move, acquiring new targets as you mouse over them. Doesnt matter if you right click on enemies or the ground, the behavior will always be the same. If your mouse is over the ground, you will move towards it, if your mouse is over an enemy, you will move towards it and attack it. So now in 2.4 you will never have to think about where you're clicking with abilities. The behavior is always the same. Which means you can always hold down right click forever and move through the entire game attacking and moving and acquiring new targets, no matter where you click initially.
Additionally, quick casting abilities always functions like this now, no matter if the ability is in your right or left click slot. You will always attack or move or attack and move depending only on what your mouse is over, so long as the hotkey is held. This effectively solves paladin spam clicking (along with all other melee classes, but paladins are the ones that struggle more since their melee ability MUST be on left click)
Left click behavior is changed but slightly less so.. If a target dies while you're holding left click over them, then you will stop attacking - UNLESS you move your mouse over a new target within a short timeframe (like half a second maybe?). So holding left click is more viable, however you won't always have the same degree of certainty as you do with right click or quick casting. So paladins can solve this issue by simply using quick cast as it will be much easier to know what you will do when you press an ability, as opposed to having to worry about a certain timeframe to mouse over a new enemy.
