As regular feats, they free up some feat space. As legendary, they're pointless -- unless you're expecting people to LTR to use them or run "gimpy" without the secondary line they usually take.
AC+10% is so pointless for DPS that it's insulting. It often doesn't even matter to a tank unless it's very seriously focused on increasing AC.
Substantive? Suggest bear & wolf can use all of the other's tricks (eg. tremor wolf, snowslide bear). Bonus points for an extra hilarious snow-slide animation for bears -- it's a bear necessity!
Too slippery? maybe bear = 5~10% attack rate and wolf = strikethrough with 2H (or even just increased 2H attributes as bear without strikethrough).
Fluffy? Runspeed/bear & HP/wolf work if you want to provide a feat to be taken when there are no other more substantive feats to take. AC/wolf .. uh, no .. make it at least a little positive.
LD is becoming the tree that gives a laundry list of pointless buffs. "Chance-of" does not work for DPS (and dodge is also chance-of by nature). KD-immune is fluff. If you need it, you've already built it in via other routes. Same with a short fort save buff -- when saves are already good enough a little more for a short time doesn't matter.
Extra mitigation is nice for a tank. A tank is fine with chance-of, but LD is not a tanking tree. A DPS that tries to play those odds is called a pack-stone. DPS have to easily be able to deal with whatever whether or not the buff fires and thus who cares if it does or not?
It looks like your desires are "unstoppable theme" and "not useful". Not checked on Lam, but guessing it's a 15 or 20 DP gated core; 15 is kinda OK for fluffy. If 20, it should be at least a little useful.
Useful: "True Freedom of Motion during Action Boosts" (nothing can stop you -- not boss chains, not earthgrab, not druid gust of wind, not even knock-back from LOB or Air Elemental). Too much? How about CC-Break on Action Boost (without any duration effects).
Fluffy: "boosts grant 30% action run speed while active". Still thematically unstoppable in a "hey, wait for me!" kinda way. Very fun. No change to combat power.
Seems awkward. I don't know any casters with 10000<SP. Perhaps "On zone-in or shrine, gain SPx5% Temporary SP. When used up, gain nature's resurgence." Same net effect, but casters can actually see the gain on the UI and when it's about to be used up. It also scales better if there comes a day when casters do have 10000<SP and regrants on shrine to provide more free buff SP.
