Because that was the real damage increase (64 to 90 at level 1).

People speculate that it's stated as 30% because 64 is roughly 70% of 90, but personally I find this sort of thing very confusing. When the 30% buff was first announced I expected the level 1 damage to be in the region of 83. But of course SC had to say that it would one-shot Minions meaning that the minimum level 1 damage is 90.
