Well, one of the most serious problems with having a vigorous experience of God is that it seems so overpoweringly important. The equality runs up and down and sideways, all the way throughout God's purposes. Our worrying about such things makes for a poor witness before others. Sure, they're that way too, but they expect something better from those who say they believe. This attitude causes the Body of believers to become less effective in using the gifts God gave it.
Rankings block the way, as a strictly practical matter.
Pulling rank has proven to be a special problem with renewed Christians in a dead congregation. Such an outlook is from Satan himself. Satan likes it when you do his dirty work for him by playing the power game. Spiritual experiences are good things to have. But they're not a measuring stick.
