so your saying it is spam casting? i was answering your question about casting in manual.
so, what spell is it getting blocked by? would be red error msgs in your eq chat, or what other buff is someone else casting to overwrite it?
what lvl are you?
what other classes are in your group?
are you saying it is casting Brutal Ferocity then casting Shared Brutal Ferocity in a loop?
Please PM me a screensnip of your mq2bst window showing that.
from the FAQ
Q. Bst is chain casting something?
A. There are a few lower lvl / mid level buffs that eq/mq2 reports stack that do not. You either have this situation or some other issues. I would suggest checking for the red error text that eq gives you to tell you WHY it didn't successfully take hold and then go from there. You can block anything you don't want cast. This is a built-in everquest feature - right click on the buff and "add this spell to list of blocked spells" or go through the eq menu -> character -> blocked buffs
