Nice guide! I've been xbowman for my entire c-rpg career an I still learnt new things ^^. For example the weak spot of shields. I had no idea it's in the middle of the shield, always figured it's just luck wether you shoot through or not. I also don't find first person all that useful, but that's just a matter of opinion.
Overall, I think it's an awesome guide from one of the best xbowers in the game. What more do you want, guys? ^^
