Maybe you could tempt us with something else

"It's a level 3 racial enhancement, it doesn't need to be the shining star of endgame. That said, a lot of people can and do use Displacement throughout the game, and if you find yourself not needing it as you hit higher levels, it's fairly trivial to reset the tree and spend those points elsewhere."
Since people have pointed out the useful/uselessness of displacement in reaper or even as an enhancement tree choice that isn't very tempting, maybe an increase to dodge and dodge cap of 3/6/9 would be generally a lot more useful. I've always thought rogues are quick, greasy, super nimble, tricksters and that something like a high dodge would be a unique way to mitigate damage if they can't massively improve their PRR/MRR, or AC.
I might also suggest a change to, or a tier 4 additional enh of a mass binding chains. If you can't kill a bunch of mobs within the timer of the attack you've drawn a massive amount of aggro that seems as an assassin rogue, you shouldn't have. But if you could slow an entire mob allowing you/your party to flank and work them down it would be a nice melee crowd control. Maybe the math monkeys can figure out if it's better if say we were to remove the light weapon damage so there wouldn't be any consideration of what you had in your hands as this is a separate chain weapon, but instead made it a no save binding chains it would be pretty unique to the tree and for a different kind of crowd control where you wouldn't require a caster as much.
Why do we have all these trap parts if it isn't easy to make a trap that's just as effective against mobs? With all these new rangers around does anyone ever use spiked growth or is it just more annoying bush? Can't things like this in game meant to help crowd control be useable?
Just a couple of ideas to add some balancing of classes and game play if we wanted to try and solo or be more helpful in groups.
