Its cool to hate on LFR and you wanna be cool. I would like to hear why you want to avoid LFR.
IMO if you get upgrades from there you should do it. For weapons and trinkets at least. Its not that bad the first few days after reset.
Even if it seems you are doing fine with lower gear that just means you could do more with better gear and the run would be done faster. Its just like those ppl running w/o gems, enchants cause they can get better upgrades and its not worth doing it for the current gear.
