Leapfrogging

[Rogean]

So I'm curious.

People who played live back in the day, on servers that did NOT have forced raid mob rotations, how did the GM's there handle a situation where Guild A is clearing trash towards a raid boss and is completely leapfrogged by Guild B which rushes to engage the mob when Guild A sits down to med. Obviously this is one large reason we are hesitant to go with a first to engage policy, but I'm curious to hear the answers and suggestions.

Also keep in mind there may frequently be situations where two guilds start clearing at the same time, leapfrogging eachother.
