hmmm I like puzzles lol but im so bad at them

If its already been put forward then disregard :
I would like to strongly recommend an apothecary class for the next release, maybe equipment could be something like Primary = chainsword with bolt pistol (or melta pistol just thinking about making it different from veteran class); Secondary = (Limited use) medipacks.
I have noticed no one has mentioned the possibilities to have a Librarian class? would this be going over the top? plasma pistol + powersword, and then have a psyker attack as secondary. The same could be said for a force commander?
and my personal favourite the Chaplain!!, could be armed with a Crozius and Boltpistol and can be a strong melee class?
I understand if this is going way over the top but i feel that these units might bring more exciting gameplay to this already brilliant mod.
For the Tyranids I think perhaps a Genestealers class would be quite interesting being fairly small and fast with a vicious melee attack?
I know people have already mentioned the hive tyrant so i'll say no more.
What do the dev people think about introducing Tau or Eldar Races to later releases?
just my suggestions.. thanks

EDIT: I've looked at the media gallery and im very impressed I can see theres already some ideas waiting in the wings.
looking good guys!
