Indoctrinates

There seems to be an increasingly overwhelming amount of armor replacers that the modders are choosing to only apply to Blaidds set and as a non-modder I'm curious if there is a specific reason when it seems like every armor set has to replace his set? Kind of makes enjoying multiple modded armors impossible as the only other set I see used as much is Nights Calvalry. I am actually curious, apologies if it seems backhanded as thats not my intent.
