No. I myself have a full set of buffers (a separate account filled with every class and buff (more or less)) and a clean setup for efficient world buffs.
But once you are in there, they are there to help you win, you are there to help your team win, and to have fun being a decked out twink : ) Certainly it makes that first death meaningful, and there are times you might disengage to save them, but if you are going to AFK out why even play : P? You can just get them again later, and leaving your team hanging isn't winning in my book.
As a side note, picking good fights is critical for any player, buffed or not, if you have to run you made a mistake or were outplayed. There are also times to just go straight at the EFC if you think you can kill him, even if it will cost your life.
