Swimming a ways back upthread for this one.
Do you have similar problems with a high level fighter? After all, my 10th level human fighter can have more hit points than a giant or an ogre, things that are obviously much more tough than I am.
If it's okay for a high level fighter's ability to be a graceful dodger (which is basically what this is) why can't the pixie have extra hit points in exactly the same way? How is that lazy?
The only way I can see this as lazy is if you insist on only one definition of what hit points represent, which has never been true in any edition of D&D. Hit points combine all sorts of things, one of which being a graceful dodger. So, why can't a pixie have 50 hit points instead of an insanely high AC? It achieves exactly the same result.
If you are fine with no mechanical distinction between the Juggernaut and Gambit then fine this was more of a philosophy in 4e where there were fewer (none) subsystems than in other editions. For me aesthetically it feels lazy and, besides me as DM describing it in different ways, doesn't in any way mechanically differentiate between the two. I mean if it's a relentless fighter were looking for let's stick him in the hit points category too, instead of doing auto-damage let's give him extra hit points each round so he keeps on going... now that's relentless. In fact let's model everything with hit points, it's simpler (though it will probably make for a more boring game because there is little mechanical differentiation in my choices)... See it's not about whether something can or can't be modeled a certain way, it really just boils down to whether any individual likes or doesn't like it and I personally don't like modelling Quicksilver, or Gambit in the same way as Juggernaut and the Blob.
As to why I don't like the feel of the "more hit points" mechanic to model quick dodges and parries... again, we have powers like the GWF auto-damge on a miss, so it doesn't feel like you're actually dodging anything against foes like that, it feels like you are being whittled down regardless of how the DM dresses it up. Regardless of what some believe in my experience how mechanics are presented and constructed affect the feel of the game... regardless of how you dress the fiction up.
