I agree with everything. Also in inferno you can freeze the rangers and literally move away and they won't attack you again. I only figured that one out after watching a stream after I had got my infernal cape.
Zulrah is easy enough with the normal mechanics. For a server that wants to replicate OSRS should try to make bosses as close as they can to osrs. Zulrah is a joke in that department where you just stand in 1 spot the entire time.
Also is there a list with the monster weaknesses anywhere? I know osrs on wiki isn't very useful because a lot of them are changed on here. I tried to use monster examine from lunar spell book and it didn't work.
