Proposal
Add additional vfx, sfx, and animations to telegraph when an NPC will block or parry.
Details/background on your proposal
Self explanatory. In world of magic the exiled boss has a move where he gains (brief) immunity to damage. This is signaled with a glint visual effect. The minotaur, his neg rep counterpart, also uses this effect when he uses his shoulder charge move where guess what, he takes no damage while ramming people. Something similar to this can be applied to AO when an NPC is blocking to signal to players that they will take reduced damage if players hit them.
Reason to add/change
NPC fights, especially bosses, can be very frustrating sometimes due to the random block and parry mechanic that they just spring out of nowhere. This feature should address this without having to overhaul or remove that function and make extended fights seem more “fair”.
