The new offense tree is so fuckin OP, 1.5% more damage, and 6% more if under 40% health, more attack speed and more armor pen than old tree, while other trees got nerfed. 1.5% and 6% stacks multiplicatively, same goes for defense tree, multiplicatively stacking means MORE for increasing stats and LESS for decreasing stats.
