no need too upset Robin
everyone will make mistake in raid (for me ,i make raid wipe in past for my fail pull for adds)
what we need to do is to learn from mistake
i think RL felt angry  becuase u make the same mistake in same raid just after 1 week..
u know bluc aggro is very danger for us in raid
mt lose aggro = dps die
we wipe 1 time = 30 min to do CR and rebuff our raid
So thats why RL will  have bad feeling in that time

iam not officer so i cant give u permission to let you back to RF
but i think our officer will understand and give u chance

to know more for rng skill or spell....
u can ask colourtiger/freewind/nathans/nemo to get more info
they are skillful and have many raid exp

personally, i will say Robin is a nice and polite ppl in guild
just need to improve his raid skill
