SE has banned people who have posted on youtube videos of 3rd party tools. But it's rare and far between. But if it gets bad enough where it is a clear advantage they will lock down the code.
If a timer goes off to avoid something they have said that crosses the line.
If it is up to put icons in a different place they don't care.
Sadly SE has taken a stance of DADT, Which will sadly blow up in their face at some point.
I very much disagree.
When I had more time. I was doing all EX content as it was current. Never used 3rd party tools.
All the console players that clear it do it without using 3rd party tools.
Just people some people aren't good enough to play without cheating or they need the crunch doesn't mean everyone does.
At one point my raid group had one person who used act, There was also one player who really needed help on how to play he want from bottom DPS just above me as a Warrior. to 2nd DPS by the info the 2 of them worked out.
But I as a warrior knew my job 95%, and my BRD my main DPS I was good with. my WHM I was happy with my over cure numbers/DPS But act didn't help me get there I already was.
