Not quite sure I agree with this. Human PM is still one of, if not THE strongest race/class combination, with the only real competition being Human or WF FvS. Also a pure Human Cleric is very powerful too. Finally, a free-to-play Dwarf (or even Human) barbarian is an excellent melee as while a Half-Orc may give more DPS, they are noticeably less sturdy.
Although for melees, if you are interested in pure DPS and nothing else, Half-Orc and Half-Elves are the best choices.
