A better way to choose party members would be quite helpful, but change it now would not distinguish a good and well aware healer from any other average healer. I see it in the raids, many healers can't handle move/target/heal/self-healing.
My complains are pointed to how the macros can be used, ex.:
I have a macro for my "Stoneskin" ability, but it have an awfull flaw, I start with <tt> and then move to <t> and finally end in <me>, but WHY:
1 - Tanks NEED to focus in agro generation, so I(in theory) will have always the rigth target while <tt>;
2 - can use it on quests npcs and companions <t>;
3 - self cast if the other 2 cast fail.
... the flaw occurs before each fight IF the tanker, or any player, has an active target. StoneSkin will not work ... since i did'nt spend much time with a work around my macro will stay like this.
