If it would work in pvp, i would be fine with it.
IF it just is a “gimmick”, screw it, it also costs like 250k…
Think it’s better to stay DPS fletcher. Don’t recommend to become CC fletcher.
You could use the silver to up your magic arrow % enhance attribute.
It’s still 5 secs at lv. 1 I won’t try to go lv.2 though
I shouldn’t have leveled mine.
Well, you can switch it on for pvp and off for pve :).
The question is: does the silence proc.
It says 50% increased chance, not 50% chance. If the chance is 1%, after the attribute it would be 1.5%. Thats the 250 not worth… 
Keep it at LV. 1 it’s a bonus silence with no cooldown. So why not? 
In PvP most people die to Broadhead real quick.
I believe it works in PvP however magic arrow is hard to hit without CC.
And if you have a target on CC already, putting a silencing-magic arrow on them is quite redundant. Rather get 2x magic arrow of 5s CD.
Use it defensively, drop silencing magic arrow at your position to prevent swordies from attacking you.
I’m not sure why magic arrow has a silencing attribute.
Oh 
that’s too bad. Good thing it’s a useless attribute.
It’s only good for defence, to prevent melee classes like swordsman from attacking you. But you have to put the arrow at your feet/close to your teammate. The arrow stays for 10seconds, so you have a 10s silencing position.
Well, you know, im a scout.
Im coming from hide, trying to pick valueble party members of the opposing players or a glass cannon with broad. I think thats my job.
Healers, nukers etc. 
If i get a fast procc and remove that player for a few seconds from battle, it would be cool.
Or i nuke with DMA.
I think you could
fire magic arrow with silence close to your teammate as defence -> hide -> go broadhead player. However if someone gets hit by the arrow you will be revealed.
