People, actually read a thread before posting in it. The title may be kind of misleading, but he did not in any way say that Hashirama has nothing apart from self-healing and Mokuton. He merely said that we haven't seen more and most likely won't see more of his power.
For the Mokuton part, I absoulutely agree.
We don't know to what extent Hashirama could use it, but Madara's version is already impressive enough. It wasn't said for no reason in the third databook that no technique is as multi-purposely usable as Mokuton.
