I never denied that our Raid has deficiencies in execution, damage, healing and tankplay compared to a CE guild. Otherwise we wouldn't be stuck. I won't link logs because I don't need anyone pointing out that player X or Y is underperforming for his or her ilvl, that is pretty obvious from WCL. But as stated several times in this thread, on this level you often only have the chance to take with those underperforming or to cancel the raid entirely.
The funny thing is that on the one hand people in this thread claim that there is no grind, which is imho subjective. On the other hand you state that those players don't even switch professions to JC/LW or BS or Tailor for good items as it is only 20k per switch or farm benthic gear with sockets.
From my perspective this is expected from players in Top 300 guilds that clear the raid in 4-8 weeks with CE. They need this to push through the dps checks and to counter bad drops. However if this is expected from a low tier mythic guild that will not achieve CE, to progress past the third or fourth boss at the end of a tier this is out of proportion.
Due to omniavailability of high level gear and titanforges from m+ and the chest most of the fights are tuned with this ilvl inflation in mind. However this negates any positive effect from low tier guilds getting mythic items enabling them to finally kill the next boss. Especially as most of those players are already overgearing HC if they complete a weekly +10 which means that the additional ilvl from mythic is not such a boost to push the raid far ahead.
The other funny thing is that some CE raiders do not understand that it is no problem for guild like ours, not to get CE, we are happy with slowly progressing through the raid over the tier. The problem is if you are stonewalled very early with almost no chance of further progress. This is what kills motivation and people get bored or burn out.
In addition due to the seasonal item reset it makes zero sense to keep progressing the previous raid tier with better gear from the next raid as it used to be in the past. Soon EP will be an empty wasteland like Uldir and CoS as there is nothing to get, only BoD might see some visitors due to the Jaina Mount.
