Below is a character from the campaign I'm running. During a conversation tonight with the other PC's about the DFRPG system the topic of this character came up and we began to second guess it's layout. After looking further I think everything is good, but I figured I'd run it by you guys to be sure. The character is the son of a mortal woman and a Fetch, making him a Changeling (YS pg 74). Please take a look at the current character sheet and then I'll explain in greater detail after it.

Question #1: Is Human Form something that can actually be taken here? According to the book it grants +1 Refresh as long as "you specify at least 2 points worth of Supernatural Powers". The character constantly uses -4 Refresh in Powers via his Modular Abilities (Which actually uses -6 Refresh due to the -2 Refresh "cost" of Modular Abilities.). The thing is, he is never in a "Regular Joe" form. His "resting form" (a.k.a. "I'm in this form unless I otherwise specify.") utilizes Powers via Modular Abilities. So can you still gain the +1 Human Form bonus for having the "capability" to become a "Regular Joe"? Even if you never choose to do so? The reason this is important is without that +1 Refresh from Human Form his character would be using -10 Refresh, which would make him a NPC.
 
Question #2: The character's "resting form" (Mentioned in Question #1.) uses the Physical Immunity Power (YS pg 186) at a whopping -8 Refresh, however, this is mitigated by attaching The Catch (YS pg 185). The Catch is Cold Iron as he is a Changeling with Fetch heritage. Since he is protected from everything except something specific he gets a +0. Then, since The Catch is something anyone could reasonably access (cold iron) he gets a +2. And finally, since pretty much anyone with knowledge of the supernatural would know a child of fae is weak to cold iron he gets another +2. This means he is able to take the Physical Immunity of -8 Refresh at the cost of -4 Refresh. His Modular Abilities has just enough to cover this. He sometimes switches to something like Inhuman Strength (YS pg 183) and Supernatural Toughness (YS pg 186) for a total of -6 Refresh. When doing something like this we've been playing it where The Catch only gives him a +3 Refresh discount (Since Catches cannot reduce the total cost of your Toughness Powers below -1 Refresh.). And if he was to take something like Inhuman Speed and Inhuman Strength he'd get no Catch discount at all as he has no Toughness Powers taken at that time. All of this seems to be how it should be played, but I wanted to make doubly sure.
 
At the end of the day the subject was brought up, because I think the other players feel a bit... "un-needed" with him around. His base Skills (As you can see above.) are set to be super high in regards to Social capabilities. Then if he needs to be combat oriented he just shuffles the Skills to be so and throws whatever Powers he needs at the moment onto himself. He does not play the character as a "ball hog" (To use a basketball term.) on purpose, but I think some of the other players may feel the character lends himself to be so just based on his design.
 
We're almost to the end of our second campaign arc, so unless something in the character is actually wrong rules/mechanics wise we won't be changing him in any way. I'm mostly curious in making sure the character is "legal" and then seeking advice on how to make sure the other characters don't feel like they are sidekicks to a one-man show. Sorry if any of this seems super simple, but this is my first FATE game, first DFRPG game, and first time GM'ing any game system at all.
 
Thanks in advanced.
