1. LFR is the only 100% inclusive option so it's there to serve the niche it needs to.
I don't agree that the game needs 100% inclusion. This is exactly what caused the downfall of the community and brought about the, "toxicity" we see today. Being able to get into pretty much any raid with relative ease - even in normal/heroic - without any consequence for your actions is the problem.
2. People were upset with WoD LFR for good reason.
Why? The only difference was weaker gear. Why did you need very powerful gear when you don't actually need it to clear the content?
Good job.
I get a little bit of joy seeing the same people attacking anyone anti-flying or anti-LFR when completely different people are trying to defend vanilla servers and ML. It shows they're just as toxic or worse than the people they whine about.
