I seen there is set rule for WoW Classic Raids that when anyone zones in instance timer starts so when you have like 40 man Naxx speedrun guild going for speedrun one guy just can just zone in just to troll and kill the run in the start and that is not by any mean good for anyone doing these speedruns.

Can you guyz change rule for Classic Raids for zone in timer starts to 1st trash pack pulled for timer?

There are tons of Private Server guilds that are to do these speedruns and this rule will just kill their run.
