Not all the tiers follow that logic.

The idea is that talents are now substantial gameplay choices.  For example, the tier Youshi referenced for Warlocks (75), all 3 relate to survivability, but strongly differ on how.  Burning Rush gives you an on-demand sprint, at the cost of a small DoT while active.  Demo Circle grants an even more powerful movement movement, a teleport, but requires setup and has a cooldown.  Both of these are focused on avoiding damage to survive, but differ on how.  Dark Pact, on the other hand, grants a fairly substantial absorb shield.  It has a longer CD than the other two, but can be used to effectively tank certain things instead of avoiding them.

All of them have a use and a fundamentally similar role, but they differ in the gameplay involved.  That's the point of the new talents.

It makes sense in that it does make you have to change up your talents it just seems like a lazy way to go about it.

Go watch the fireside interviews with the Dev's, they go into detail explaining why the put the talents where they did. I kind of like what they did. Makes each choice actually a choice, idk about other classes but DK's never had any choice in any talent. Ever. This will change that.

Yeah.... I'm really hoping none of the lock ones go live anything close to what they are now.  Teleport, Burning Rush or Sac Pact (not even sure why they renamed it).

This shit is nigger as fuck. All they did was jumble the talents up so you have passive healing talents on the same row as movement increases. I wouldn't be surprised if they had a program that just randomized the talents to be on different rows. GTFO here.
