So get Resolve. After you can move down to class perks put 1 point in Counterweight and then start time training Stall the Advance. After that you can go back and for example finish Pressing/Decisive and then focus on Passive protection wards. Among other AAs buffing combos like Improved Guard Destroyer (decreases CD of the combo), then Improved Last Stand (decreases CD of your bubble by 1 minute) and so on...
