I understand how frustrating it can be, I was stuck on T5 for over a month before switching server. However, I don't agree with nerfing it anymore. People do T5 to get to Second Coil. T5 helps you learn to react to much harder hitting and more unforgiving mechanics, how to deal with things properly as a group, and also develop the patience to wipe repeatedly for hours just for 5% progress on the healthbar.

So yeah, I realise it's a pain, but it ultimately helps out.
