They do. I've played two to hero. There are some really cool perks. But they are perks.

Unblockable damage is arguably their most powerful perk, but it is offset by less attacks per round. Anti-air shifter stuff is useful too. Especially nowadays where air shifters comprise of a quarter of a hero's pk range.

All I was saying is they are not an easy class to play and are mediocre in terms of their PK abilities. If you want to pk with a melee class, arial/felar assassins, giant sword specs, orc berserkers. There are much better options.
