Amen.
My own most recent experience is healing end-game raids in WoW, BC through Cata. No healbot automation, don't try to lay that BS at my feet. Just raid frame UIs to display health bars and vital information (ie. critical buffs/debuffs and timers) where I can easily see it, and mouse-over casting macros, so I can quickly and intuitively respond.
I was able to spend most of my time looking at and playing the game itself, not hunting and clicking through UI bars to achieve what I wanted. I could keep heals rolling off a tank, maintain CC or interupts on a mob, debuffs on the party would barely have a chance to tick and you'd never see me standing in fire because I was too busy squinting at icons to maintain situational awareness.
And no, this was not spamming one uber-macro keybind, I still had to think about every cast and perform moment to moment triage. Lttle heal. Big heal. DOT on a DPSer, but he can wait, he's third priority. 5 seconds left on the CC. Things are stabilized, regen some mana...KICK THAT SPELL NOW NOW NOW.
By comparison, healing in SWTOR up to the 30s has been a miserable and un-enjoyable experience. Maybe it's just my hardware (an 'internet browser' mouse and a stock keyboard), but I have ANTI-mouseover: if my cursor is left hovering over a portrait/UI nameplate after I click on it to select a target, my keybinds stop responding. So to heal, I'm like a boxer sparing with my UI, jabbing, ducking and weaving to achieve my desired result. It's getting very old, very fast.
It cannot be stated enough: we're not whining for automation, we're gripping about targeting. For you DPSers spouting L2PLAY at us, imagine if you had to maneuver your targeting reticle with the arrow keys, like old FPS games that didn't support mice. Stop your complaining, mouse aiming is a crutch for bads, I used to dominate multiplayer Doom with just the keyboard, your arguments about being able to quickly swap targets are invalid.
It's really very simple. If healing means spending more time fighting with the UI to get feedback about health and debuffs (and then acting upon that information), then it's more frustration than fun. And if frustration reigns, then subscriptions drop and SWTOR soon withers and dies like so many other MMOs since WoW began (which, let's face it, is the benchmark). Yes yes yes, the game was just released, big changes are coming, great things are planned. And soon, we promise.
We'll see.
Bingo. It knocks any argument that 'macros are cheating' into a cocked hat, as the Brits say.
