I'm only a Co-Gm, and I am going to be honest, as well as give you my opinion and vote on everything. 

Not being accustomed to "Low-Power Rps" is a slight disadvantage in my eyes, as being accustomed to more "Op-Border Rps" can give writers a heightened sense of what they are entitled to with their RPCs. However, the Jack-of-All-Trades is possible, but not preferred. We would ultimately(as I have been explained so far) would like to avoid that general sense of characters and have more defined parties in which multiple people are participating and each one has their unique or relatively unique(in the sense that some have similar skills) so that no one can be the cookie-cutter class, or be the one person to always have a item/power/skill/weapon/strategy to get them out of EVERY situation. It is less dynamic to have an RPC who can do that, rather then have actual scenarios in which a character may be gridlocked without an immediate answer or way out of the situation. 

Ultimately, reading will also be all Gm's advice for knowing what is going on in the Rp, we aren't terribly far but in the end some developments and character interactions have went on and there are crucial parts in the RP that it is only gotten from reading.

Remember, this is only my opinion, vote, and understanding. The other Co-Gm and our Lovely Gm may say otherwise however.
