Damaging any other player while invisible should immediately remove that invisibility. Wizard combination of invisibility and the scattering arcane bolts essences needs some review.On top of which now have an essence for invisibility so they're even harder to even register on the screen, even if the lag issue wasn't a constant nuisance.
The speed at which monks can traverse the map in pvp needs some review - whale monks are oppressive in the extreme because they're nearly impossible to stop and their teleporting attacks one-shot anyone that isn't at the same tier of resonance/stats.SeepingBile ticks also seem to correlate with lag/rubber-banding. Lag, particularly in pvp, is significantly noticeable when Starfire Shard is present (on anyone in the match).
