For the people going to comment on how much damage it deals. It deals about 20% more than an uncharged melee. If you're on Solar, Void, Strand, Stasis, or Prismatic and aren't using an arc melee expect 1 charge every 20-30 seconds. In ultimate content most red bars will survive the hit and you're stuck in a kinda long animation and unlike in pvp enemies are pretty accurate at shooting you I tried flying above the enemies and lost nearly 80% of my health instantly before just slamming into a rock to hide. On the note of pvp the melee does like 30 damage and you enter an extended melee animation to the point the only strat for it is ending the melee early and doing something else after using the initial speed boost.
