Couple of things, before we go further. First, can you tell us which VT mobs you're killing? I know in some places, some Apex mobs are just barely VT (like... level 125ish, I think?) with mostly IT spawns, and if you grabbed a mob whose name started with Apex, it'd be a no-brainer as to why you're missing because their stats are incredibly high.

Second, can you post your TP set for us, including weapon? Perhaps if we get a chance to see what you're fighting in we can help figure out ways to bump that accuracy up for when it's needed.
