It seems one person out of 4 running caves gets dc. I ran the elite caves an one got dc, the rest of us went on to finish the map.
Only free arcane and mythics we get in the game are red and yellow pings.

Suggest sts return all the potions used if dc. If boss spawned and player dc, then give a free ankh kit as a reward. Dc I am talking about is the server side dc.
Reward a mythic egg on 25th dc and an arcane egg on 50th dc.
