I agree, but sometimes if you write fluff or something similiar, sometimes they just have to be a little OOC
A few years ago, I used to write stories as well and whenever the characters got too OOC, I got all angry, depressed and stuff.. xD So I stopped writing and torture myself by drawing instead..
I still have to read the new Prussia story of yours, too.. Man, I'm such a lazy-ass.. =A=
