UR Character Cards at Rank X

Finally maxed my UR characters cards to Rank X yesterday. I had been purchasing Reserves packs exclusively since they were available in the store. One by one, I slowly gathered more and more UR character cards (a little over 26% UR drop rate). First to X was the Duelist, followed by the Avenger, Kineticist, Operator, Exemplar, and lastly the Krogan Gladiator. While they are very good even at Rank I, their potential is unlocked once you get them to Rank VI and higher. Some builds that I’ve run:

Asari Duelist: At Rank I, most people max out Charge, Offensive Biotics (for Biotic Warrior 6B) and Barrier. At Rank X, I am alternating between Backlash at 5B or Lance at 6A Knockdown or 6B Shield-Powered.

Angara Avenger: Sticky Grenades and APEX Training to 4. Will experiment will maxing them and putting one point in Stealth Grid. I do prefer playing the Huntress for my Stealth Grid fix.

Human Kineticist: At Rank I, most max Biotic Ascension and Barrier and take radius in Pull. I think she benefits the most from extra cards. At Rank 6, she can get Pull to 4B Radius and Double Throw 6A. I’ve even experimented with just one point in Barrier, but’s she too squishy and loses Ascension too quickly.

Salarian Operator: I have seen people dominate with the Operator but I haven't played him enough to find the right skill set. Suggestions?

Angara Exemplar: Just having him at Rank I is great because of 6B Bioelectric Focus. I am going to experiment with 6A Retaliation and maxing Barricade, using Energy Drain as a detonator.

Gladiator: At Rank X, I have maxed out pull and annihilation field (Biotic Wind). I prefer to run her with Vortex and use charged Venom shots for shield-stripping and staggering. I’m not comfortable yet running a 6A Draining Field and 6B Shield-Powered Nova build that others on this board have advocated.

Now, it’s time to buy Premium Packs and max the rest of my weapons. Good luck to everyone at getting your UR character cards to X!
