Hello there,
I don't know which effort it would take to introduce the API event "UNIT_SPELLCAST_SENT" on nostalrius which was on retail introduced with patch 2.0 but if it's not that big of a deal it would help a lot in my opinion.
From my Computer I usually get a latency between 15-25ms in general (value taken from GetNetStats() which only updates every 30s, not speaking of an average value in this interval) but when playing at peak times the latency feels like 5x higher (even though GetNetStats isn't peaking higher than 30-40ms).
with "UNIT_SPELLCAST_SENT" addon developer like myself could calculate the "real" latency while playing, which eg. could be implemented in CastingBars to enhance game experience during peak hours.
Thanks for your time
