If you think d7 is complicated just wait till d8 comes out lol.. D7 rolled out some two years ago, was it really usable at that time?...Remember all the alpha releases ,,betas,,...bug fixes and so on, and all that is waiting it's turn with d8.
My predictions for d8.
Add one year + before some betas roll out.
Add two more years give or take for bug fixes,/improvements.
So we are looking at about another 3 years before D8 is usable.
SOON this SOON that you forgot about that?..lol... So yeah see more i say work with what you got don't wait for something that could take years. D7 is OK now, could use some makeovers here/there but it's usable.
Good luck.
