The longbow skill point blank shot is in my opinion, a failed attempt at giving longbows utility. The idea of it sounds good, but the utility of the actual skill ingame is not fantastic.
It has a 2-3 second cast time which ruins the ability because you can’t accurately judge someone’s location to knock them back 2-3 seconds in advanced. When someone is running towards me, I will queue this skill and by the time it actually goes off the enemy will have run behind me which means the skill fails completely. The cast time of this spell should be cut in half at least, preferably 0.5 second cast time or less so if a Ranger wants to knock someone back, they have a rough idea of when to use the skill and how and what location the enemy will end up.
