Black Arrow is probably the most important ability for SV hunters in PvP. It gives us the potential for Lock n Load procs, which with CDs popped can lead to some semi-okay burst. Not even close to amazing burst, but you can still tell the damage increase as expected. Now, Black Arrow shares a CD with Explosive Trap. This completely ruins SV when compared to MM or BM, due to the fact that the Explosive Trap glyph adds so much utility to hunters in general. Freezing Trap --> Explosive, CC a healer AND knock them farther away. Why do they refuse to see this ridiculous problem? It completely ruins SV - you pick between a knockback and a load of damage (combine the DoT effect AND the LnL procs).
Not only that, but BA can be dispelled... kill command and chimera shot can't.
