Trickster is a great class, but I would make a few changes.
Under Archery, I would take "Archery Expertise" and "Eagle Eyes" while dropping Wild Instincts since you already have a lot of slows available you don't need faster move speed. From here, I would take "Feral Claws" which gives a bit more damage.
Under Shadowplay, I would firstly take "Toxic Shot" as it provides a good combo with archery adding damage. The "Shadowsmite"/"Overwhelm" combo is really underwhelming on the Trickster as the points are better spent other places such as Witchcraft. I would drop "Shadowsmite" and"Overwhelm" and put a point into "Toxic Shot". "Shadowstep" is also not needed as you have plenty of CC and "Freerunner" to allow you to gap close for Witchcraft abilities like "Banshee's Wail". With those 2 points saved, I would look towards Witchcraft
Under Witchcraft, you're missing out on a lot of the cool abilities. "Earthen Grip" actually is a free instant cast spell off of a "Drop Back" giving it insane utility to set up for "Concussive Shot" or teammate's combos. "Earthen Grip" combos with "Enervate" to heal the caster as well as "Enervate" increases the length of your stuns and trips on that target. "Bubble Trap" is a much more effective CC than "Lassitude" as you can not break out of a bubble, but you can become immune to Sleep. "Purge" is a really underwhelming spell at the moment because it's a random debuff cleanse. A more reliable point spent would be in "Magic Detection" which offers a bonus 500 magic defense permanently. "Courageous Action" can be taken if you are afraid of mage's sleep CC, but generally I find the fear immunity from Archery is enough. "Dahuta's Breath" is pretty annoying to face, but not powerful as you already have a lot of peel to keep yourself alive. You have "Drop Back" into instant "Earthen Grip" with "Banshee's Wail" to instant fear and "Focal Concussion" to instant stun. In the end, I would ditch "Dahuta's Breath", "Lassitude", "Courageous Action" and add in "Earthen Grip", "Enervate", "Bubble Trap" and "Magic Detection".
I love this class because it offers so much utility, sustain, peel and damage. Giving up some of the core abilities of each skillset however would not be effective to helping you win fights.
