The one potential problem I can see is that if they do that, then if you're in an area such as GWD cave north of trollheim where the snow reduces your stats and prayer fell (on the skill page) below 96 then you'd no longer able to activate turmoil. Of course they could simply make this not happen, but it then wouldn't follow suit with skills like magic whereby you can't teleport if your mage level drops too low. But yes, if they found a "workaround" for this then i'd fully support it.
