Im not saying its impossible. I control my pal as good as a single person (well if I bothered to get more talents and spells, I mean I could control the tank as good as single player, like I do with my warrior in EQ). But if you are going to be on your main 100 percent of the time, then the support toons need to keep it simple.

Also I guess with only 5 its a lot easyer to get more out of each toon. Of course you will not come near to max dps with /castrandom, but you should do 75percent of max. If you can do 100 percent with your leader adn 75 percent with the rest seems to me you are doing well. No one will get 100 percent out of all 5. And all the extra work you need to do and extra concentration to get from the easty 75 percent of max dps/heal whatever to the 85 percent or whatever you do with tons of key bindings and macros, well seems a lot of effort for minimal return. On the other hand I am very familar with wanting to get the absolute max from your toons (who dons't compare gear and take the one that is .06 percent better lol), and really why not be the best you can be.

Well we do play different games kinda, I just press a button and the mob is dead, 25 earth shocks and its over. I even have fire nova totems now but where I am at there are to many casters/ranged mobs to really test it out. And I have a main button and a "emergeny heal" and a "drop dem totems" button but ....

Also I am not saying you use the same big button from level 1 to 80 for every encounter. You settle into your camp, figure out what you need and write your single spam macro accordingly to maximize efficeny for that particular camp or even particular encouter.
