Well draco I think you have dispersion dispersing damage before all the reductions. If someone does 100 damage to a hero that is magic and bb is causing the magic damage to be blocked by 50% then the damage dispersed should be 10 and thats assuming level 4 dispersion . It certainly feels like it's dispersing pure damage. Same with bristleback. Seems like spray is dispersing pre resistant numbers. And it seems like dispersion and spray are coming through as pure damage and not being blocked by any resistance.
Dispersion is pure dmg return , bristleback is physical dmg , in answer of ur post I will say that :
if the "bugs"​ that u describe are caused by dispersion or backtrack or bristleback picked separated , than it is a bug however
if u pick dispersion + ​backtrack , or dispersion + bristleback or bristle + backtrack or the 3 of them together than the almost impossibility to kill the owner of those spells is not caused by a BUG
the mechanism ​ of the skills is structured by passive healing from % of the dmg received
the immortaility is casual for ALL dota lod version when the dispers , bristle and backtrack are picked all together its ALMOST imposible to kill except with insane critical strike (enchant totem + morphed stats + morted crit ) and u can manage with 15% to overdmg the enemy MAX HP after dmg reduction by armor .
For example :
you have 500 dmg
you hit enemy with 10 armor (smting like 40% dmg reduction) and 1000 (with max 2000) hp
if the enemy has no disp​ersion and bristleback you will deal 300 damage to him
However if the enemy has dispers + bristle (62% reduction)
you will deal 110-120 max dmg to him
if the enemy​ has backtrack and dispers and bristle
and when the hit penetrate the armor if backtrack triggered
you wont do any dmg , instead you will heal the enemy for 62% of your dmg after the dmg reduction by armor
so you will heal the enemy for 180-200 hp and his hp will go from 1000 to 1200
overdmg crits
if u have very high dmg that is greater than the enemy MAX HP after the dmg reduction by armor , you will kill him instantly no matter his skills , even refraction and abbadon ult cant do shit about it.​
