Let me just start by saying, This update was great for the Ely, finally a step in the right direction for fixing and tweaking the combat system!
During this Update Alot of Area's, Npc's and spells were fixed and corrected to ensure the original mechanics of the game are as so. This may have lead to some weird changes in what you may have become confortable with. (Great job staff!)
This is a list of Changes that were made during the recent update "Major NPC & Magic Overhaul" that differ from how original mechanics should be... (Note this update was amazing, just a few hickups):
Unlimited runes Perk for donators does not work.
Zulrah Boss has a few "unintended" issues; Namely: Phases switching is too fast, Attack speed very fast. On the good side however, minions and clouds now deal appropriate damage...
Few areas that used to have problems with "agression" e.g Saradomin GWD Kc rooms are now fixed. However a few are not (Tormented demons, all aggro on you at once).
GWD Bosses feel as though they may have been nerfed. (However im lead to believe this is due to OSRS stats being implemented).
KBD Drop table bugged (apparently dosent drop any loot at all).
Dung Monsters Bugged. (See cordo's Post below)
When teleporting away from combat, players sustain all damage taken from the time of teleport. (Should be immune).
High and low level alchemy do not work on Untradable items. (This was a common way of making sustainable cash through bossing).
Players experiencing difficulting teleporting using spellbook teleports. (see Mate's post below).
