Fatality only work well at low opts with quality members, it's been the case since ~2010. When they have the ~40 pulls they do well, they know what to do with them. Anything more than that and it becomes an un-organised mess of a clan.
They do not know what to do with higher pulls, they get cocky and let their gums flap too much - when other clans retaliate they crumble and their newly recruited members soon leave or go inactive.
Unfortunately, I do see Fatality's days ending soon. They struggled to compete with the likes of RD and EoP (#2 btw) and have resulted to helping SV. Inevitably, once the SV/TLP rivalry dies down FI will be the focus of TLP.
Time will telll...
