However, in the case of the poison, it's most likely removed from the DBCs. Taking Crippling Poison as an example, the DBCs show that it only got one animation at procc, which is at the target. The "caster animation" needs to be set to refer to the animation you want.
If you extract the SpellVisual.dbc and look the poisons up there, you'll notice only one field has a value (field 3). That would be the effect occuring at the target. The two fields before that, determine what animation YOUR character should use. In the current DBCs, both these fields are set to 0. What you need to do, is to set the second of these two fields to the animation ID of the procc, found in the SpellVisualKit.dbc (you can find the animation by either looking up another spell having the exact same animation when it proccs or is done casting, or grab the SpellVisualEffectName.dbc from an older WOW install).
