why we don't remove inhibitor turrets?

The same with the nexus why not...i feel like it is better if riot does this

if i recall correctly in smite there is a big monster which defends the nexus

sincerely i only played strife and loved that game i'm so sad it is dead he could be really superior to lol it is so sad it was well made riot even copied many things to it,this maybe the reason this game died :((((( but still had many things riot could copy like the replay system like really it was the best
