First, I like decal and never use it to UCM / ACM. I do not use ElTank. I do enjoy the buffing / mapping / xp tracking / Quest tracking and other informational tools.
MonsterMadness,
It strikes me that you are missing the entire point of AC.
Korigan,
As much as I do understand how Combat Macros have affected AC I do not believe that the vast majority of decal users use it for ACM / UCM. Decal is a valuable tool and as the Decal CoE states (paraphrased). It would be a shame to not have the vast good it can do because of a minor evil.
In every game there will be the D00d factor.
In every game there will be the powerlevelers.
In every game there will be zealots on every side.
In every game there will be macro's and exploits.
Guess what. Live with it or go back to pong.
As for monstermadness you may want to turn off Eltank and actually learn to play AC under intense combat and stress. It's way more fun.
As for me, I just want to know how to get places without remembering all those damn portals.
Edit: Forgot to say thanks to the Decal Dev's for all thier hard work. Thanks!
