I honestly don't use my fellow. I unlocked her, messed around for a few days, never did the Promyvion quests to call more often, and I'm pretty sure she's at level 31. Hell, I even threw away the pearl (yes I know you can get more). I also have very little interest in actually leveling my fellow at all.

Despite this, I know that some people enjoy their fellow, whether for fun or practical purposes (soloing and/or trials, et cetera). And I think it would be a good idea to add these commands for the people who do care. Frankly, I didn't know that they weren't there and I'm actually surprised by it. It just seems to make sense, would be completely logical commands to add for those who do care.
