If dots are stacking and mobs can take an unlimited number of debuffs that
COMPLETELY changes raiding. In the original game a mob could only have one of each dot or debuff on him and the total number of effects on the mob was limited (15?). Not only that, but there were certain dots from different classes that wouldn't stack with each other and certain lines would only let you have you of that line on the mob. For instance if there were two druids in a raid one could cast a disease based dot and the other would have to cast a dot from the fire line. The second even druid couldn't even cast a lower level dot from the disease line.
If you can, in fact, stack multiple copies of the same debuff and dot on mobs, we're not even playing close to the same game as original EQ. Is this the case?!
If this is true it is a
gigantic issue and most probably the reason that the high level guilds seem to be having a cakewalk on raids.
