You know what else was a disable? 616. 9 out of 10 it stunned those that could be stunned. It dropped to the ground those that were hit by it. This "immobilize" effect, while I am not knocking the spell, isn't the problem. The problem is that these are requirements to enhance a spell to a pre-existing level. 616 alone now does shit damage, shit criticals, shit disables, AND you throw in the fact that adepts and seers are now dodging your ass like they are shaolin fucking monks.
Also, I'm still irritated at the fact that there has been no official documentation, even on the spell review sheet, other than "Convert to SMRv2". It was the SINGLE most non-descriptive spell change out of the list. Now you know why. Because they couldn't even come out and say what the plan was because they knew it would be shit on, like what is being done now.
It's always better to ask for forgiveness than permission.
