Having the new xeno races are a nice addition to Rogue Trader. Even If the player is an experienced 40k player, the codex do not give a break down in the language of the race in question. The fact is not having a proper name generator for the Kroot or eldar either for NPC's or other wise is a major annoyance.
I personally don't really care about the rule that you have to be a 40k player to use the ork or kroot races. I'm not all that creative with names and would prefer to roll them. Guess the main point is, why didn't to add a modified name chart in Into the Storm to begin with?
