it needs a buff againts barrier champions and gameplay without champions.
the buff should be:
similar to arbalest the barrier champ should be 1 pop with the exotic and stunning a barrier champion (maybe also when a teammate stuns) refunds 1 or 2 melee charges.
+
for neutral gameplay hitting enemies with melee throw should refund some melee energy (10%) on each hit or maybe whisper of shards level of melee regen when you have an overshield.
let us build into the shield throw fantasy.
