Add-ons will be used to give an advantage to those without. As a mid hardcore-casual gamer, that is unacceptable. When I get home from work, I want to have good fun matches of PvP or some fun questing.
There will be many people downloading add-ons to perfect their gameplay (ex: 1 button presses to do normal attack, then special attack as soon as it procs, then follow up devastating attack afterwards). You people say, I just want damage meters and blah blah blah, but that's a croc of ****. Once people start adding those in, it's just a matter of time before people start exploiting with those programs.
I chose an RP-PvE server to minimize interaction with those obsessed people, but I'm already seeing some fanatics now that I'm a higher level.
Please, keep add-ons away Bioware, it will ruin the game.
This post tells me you have no idea how addons work.
What you're describing is a bot program, not an addon.
