It's LFR, it's supposed to be easy.
Really the only three bosses that don't surprise me if there is an LFR wipe is horridon, tortos and dark animus. Lei Shen to an extent too, the rest you shouldn't ever wipe on anymore unless something has gone horribly wrong.
Ana, I highly suggest learning Python. I've been self-teaching/learning it for the most part.
There's also codecademy's course http://www.codecademy.com/tracks/python and a free book for it http://files.swaroopch.com/python/byte_of_python.pdf
I cannot suggest codecademy's courses enough.
