At this point will FFXIV collapse if all mods and third party tools disappear?

[Absurdity]

The MMO aspect of a MMORPG is far less designed than the RPG aspect, these players are online and participating in the game world, just not in ways you seem to want them to. What’s the issue with this again?

Where did I say that I don't want them to? Read my reply again and what I'm replying to, it's not rocket science.

I sometimes seriously question people's reading comprehension. Where did I make a judgement on the second life/IMVU players? Unless we now assume that putting something in caps for emphasis is a judgement.
I simply stated the fact that they're here to play dress-up and chat, so if you take the dress-up part out of it by banning mods they will go somewhere else, because they are not here for the MMORPG part, they probably couldn't care less about the gameplay.
