The reduced healing and overshield amount from the stasis shards makes builds using that part of the subclass feel worse. While 50% damage reduction on the overshield should make up for it, the slower gain cancels things out somewhat. Taking enemy fire makes the whole process worse, as oftentimes that incoming damage is enough to cancel out any benefit (aside from the melee energy, of course). This is a problem on Behemoth in particular, as much of that kit works best up close and personal.
