Why are current Alliance Raids not available for Minimum Item Level runs?

[Jeeqbit]

I've seen an alliance put together for this only to discover it wasn't possible in Shadowbringers.

Min ilvl will change nothing about crystal tower. Its missing mechanics are disable, so lowering dps does nothing.

That's not true at all. I was in a server that did them minimum item level and we were in discord. We wiped multiple times and had to learn the mechanics, discuss strategies and do callouts whereas you don't need to know them at all normally. In fights we didn't wipe on, we almost did with healers down. That was before the stat squish but I don't think it affected ARR that much.

whats the point with min ilvl alliance raid ?

within or without, its a casual content where its impossible to wipe

Wipes used to happen all of the time in Weeping City and we definitely wiped in the new one when I did it on patch day.
