As a solution to this, I'd suggest adding back like 30% exp from total number(based on pre-nerf exp rates), this would currently make boss tasks worthy to do exp wise, because they are as worthless to do as a regular task right now(exp wise).
And would also like to suggest kind of an update for duo slayer: If it's a boss task, as long as both members did damage to the boss, both get 100% xp drop, and if it was only 1 player to damage the boss and the other one to just staying away(for example lvl 3 skiller doing slayer), then the player would receive the 25% of the xp for just being around. Regular tasks stay as they are.
Not quite sure, but in my opinion/my perspective, this would probably somewhat fix current slayer problem, aka balancing out the xp rates. Because im genuinely not motivated to do any more group boss tasks(or any other slayer task) coz, sorry, i aint bothering ppl to help me with a boss that gives me 25k xp drop for a kill, when previously it was 250k xp. i know 250k is alot, but 90% xp nerf is just :shit:
