#1 speculation, dismissed.
#2 slippery slope fallacy, dismissed
#3 Strawman, no one is making that argument.
Try making some arguments that don't fall into obvious fallacies before requesting that people make informed arguments.
#1: Already stated I don't have hard proof, but I want you to prove to me that +5million WoW players use addons. I still believe in my first point but we'll follow court rules and say the point is tossed due to lack of proof. Lets look at the others, shall we?
#2: Fallacy? Raiding guilds all require at least a DBM equivilent, some require more. Allowing addons to TOR will bring similar functions and the same results. Saying players don't have to use addons then requiring them to raid is an invalid argument. (I'm not saying its better for the raiding community. I'm saying the argument itself is invalid)
#3: Check the MANY posts on these forums from people stating the exact thing that a lack of DPS meters and the like will keep bad players hidden and able to stay bad. People are making the argument.
