I think it needs to be adjusted
Currently, channeled magic spells can’t be used. This puts classes that use one at a disadvantage because most are dot specs like shadow or afflic. So they can do absolutely nothing to a DK while the shield is up
The channelled spells should still deal damage, and just be absorbed by the shell. They shouldn’t get to immune the entire spell because it’s channelled.
I understand immuning the cc component, such as ray or frost, or mind flay, but the damage part of the spell should be absorbed, not immuned.
It give specs with a channel even less of a chance. They can’t even help break the shell early if the DK is attacking someone else. You just have to afk until it’s down, or someone else breaks it
This isn’t the biggest issue with PvP obviously, but I just find it odd that the shell is an absorb to most casters, but if you’re a dot/channel spec, it’s an immune to you instead. You cannot break it in any way, and must simply wait for it to run out.
