The viper sting comes out first, so don't underestimate this DEBUFF, which accounts for 12% of all your damage (about this value, if you keep filling it up). For hunters, returning to the blue talent is not your first consideration. The talents of returning to the blue, such as the knight's aura and hammer talent, and the mage's ice skills, cannot be superimposed, so the talents you add back to the blue are of little use, mainly depending on the timing of your guardian's transformation. Weakening armor-piercing is a very useful skill, but it is useless to point too much. A little is enough, and a little resourcefulness is enough. Generally speaking, the online point method is more cost-effective, but it does not rule out that your equipment has a little error, and bringing some non-mainstream talents will lead to higher damage.
In fact, it doesn't matter if the CD of Black Arrow is a few seconds shorter. It is pointed out that three explosions can make up for this little damage. This talent is mainly used in PVP traps.
The last question, in fact, it doesn't make much difference if the click rate is low. No amount of hit overflow will help. Less agility, higher crit rate. If there are few hits, you can choose. If you miss an ordinary shot, the next ordinary shot crit is almost equal to damage, and your hit itself will not be too low. Of course, if you have FM plus or something, you'd better add, if there is no way to increase the attack.
