IM me at any time when I'm online and I have no problem showing you the ropes.
I have a LOT of playing time with Sedna and Unclean Beast, so I can help you the best with those. I have played with and against many extremely good Oak, Regulus and Rook players, and I can tell you what their builds are and what to do in certain situations. Erebus is well... I don't like him very much so I don't know much about him. Queen, well, I've played a few competitive games but not much.
I have a fairly good understanding of the gamemeta and I can give good advice about most things.
I'm not a pr0 though (I can hold my own if I'm playing with my oak friend, but, we'll still lose eventually), so don't expect me to make you l33t in a day
