I would have assumed this would have been looked into Mod17 considering the new 1000+ iLVL gear with abundance of CA.
I know this has been going on for years and it seems now that it's intentional. However, if it is, are ranged classes compensated for it and why doesn't cryptic clearly state its effects?
Anyone who is confused regarding the above, then please briefly watch the below video. In summary, Combat Advantage has a small (more or less melee radius) within which it procs. Outside that radius, ranged class are unable to benefit from CA, hence all that CA that you have build is useless. So you either stay melee and do CA damage or use the benefit of range as a ranged class but get no additional CA damage.
