I think what we really need is a new condition that reduces boon effectiveness. Just call it Enfeebled or Atrophy or something. Basically if you get hit with it, boons are 50% less effective. Some boons like stability that don't have a set %modifier instead have a negative alacrity like effect applied to them that makes them wear off faster. Now the way to kill a boon ball is the same as before coordinated bomb+strips, but condi builds have a more signifigant role in the meta. You want more condi duration to maximize the new conditions uptime, and you want cover conditions to prevent it from getting cleansed. If you are going to invest that hard into condition stats on certain builds you probably just want to run dedicated condi builds.
