[@Hank] I respectfully disagree. 

'Fun' is a matter of opinion, and I quite enjoy the idea of being at the head of a large-scale battle between two of the 40k factions. Hell, it's one of my major hobbies. I do it all the time. The thought of doing it from the first-person perspective is something I very much look forward to.

As for any question of my capacity... well, I'll bite my tongue on that topic. However, I will say that I find it very small-minded of you to think that someone is 'bad' at roleplaying just because they enjoy playing powerful characters. Power is just another defining aspect of a character. Personally, I think having a character with access to large sums of power is more fun, because it gives me access to more opportunities to explore that character. Anyone can be weak and powerless, that's easy, and so is depicting it. Sure, having power is also easy to depict. What's not so easy is controlling that power, when it's finally challenged.
