Sounds interesting, didn't play EQ2 though, so not sure. My only caveat with that type of a system (its sounds like anyway) is it may become too commonplace and and formulaic and too much of a requirement for everyone to participate in and lag spikes might ruin the chain or some newb. On the other hand if the complicated stuff is kept to the major spell casting classes then hopefully only people good at that kind of thing will keep up with it to end game. As I'm not sure I'd want it to be a requirement for everyone, for every tough encounter.

Although I'm definitely not averse to more advanced tactics. And maybe something along those lines could be developed so long as it didn't rely on the weakest link in the chain kind of thing (by making several people able to complete each step).

I can just see it:
"Dude, hit your ice spell, ice ice!"
"Dude, wtf!"
Group dies.
"what happened? Sorry was afk."

So to sum up, tough encounters, but encounters that don't exploit the weakest member of the group. I like it when the good players can take up the slack.
