That's not even close to being true.There's many things that can contribute to having an easier time than the 1-2 hour LFR ques. 1. Having a guild. Want to have an easier time finding a group? Organized raiding. Makes it easier than LFR. 2. Premade group finder. This is going to vary and may or may not be easier to find a group than LFR. As a healer even with my lowish Ilvl I get accepted plenty and with that happening the group I join can usually clear the first 2 bosses before my LFR que would have even popped.
Are you trying to say LFR is easier to find a group because all you have to do is que for it? That's not even close to being true. Join a group that's already almost full (usually 2/3/9 or 1/2/8 or unless it's a larger group) and bam. One takes 1-2 hours, the other takes 5-10 minutes/10-20.
This is the important part though: This also depends on what you're really trying to do. If you're trying to kill that one boss you missed during the last pug or the last raid day in your guild for that one piece of loot, obviously LFR would be quicker because you can select which area you want to start in. If you just want a fresh run for whatever reason (collecting tomes, getting gear, etc) than pugging through premade would ultimately be faster and even easier.
