The reason why dronacharya was soo repulsed by Shakuni was because ever since he got the future memories in this world , nothing was going as it was supposed to be going , and no memories from his past life could help him in his journey to the top.
Dronacharya was someone with future knowledge just like Shakuni, however the difference was that he was not the reincarnator himself .
On the day the third system update happened in Omega , and the VR Olympics and other expansion packs were announced , Dronacharya was caught inside the game due to a technical glitch and unable to logout during the duration of the update.
The system update was a time where , nobody was supposed to be inside Omega , however unfortunately for Dronacharya , he was the only exception.
