Yeah I admit I took this one a little personally. I guess it's because I was really excited to see someone post something new in IC.
I like both your characters and Glaydr's but I would prefer 4 people playing 4 characters more. It's not that I don't think that you can't make characters distinct but I just think that having more people brings in more perspectives and therefore more opportunities to roleplay. I also have an innate trepidation about GMPCs. They are really difficult even for the best GMs. Both of these attitudes come from my tabletop experience and I admit I am inexperienced with PbP. The two characters thing is probably much easier in PbP.
I overreacted but I would like to note that he did seriously break protocol by posting in IC without even talking to the GM first. That's just disruptive and, since he didn't delete it, it's now there forever. It's like the Star Wars Holiday Special of our campaign now; it's a dumbass thing that happened early one that we hate but we can't get rid of it, so it's still 100% canon.
