I still think that a good way to increase pking activity is to increase the minimum risk required depending on your level. this way we don't add extra money into the economy but we guarantee players that a kill in BH will grant them X amount of money if they are combat lvl Y, as opposed to no loot guarantee if they don't use BH
example:
1-30 = 25k alc value minimum to use BH
30-50 = 50k alc value minimum to use BH
50-75 = 75k alc value minimum to use BH
75-100 = 100k alc value minimum to use BH
100+ = 200k alc value minimum to use B*
This means that a lvl 101 who kills a lvl 102 will be guaranteed 200k+ if he ALC's the gear and since just about every items in runescape has a higher street price than it's alc value, players are looking at more than a 200k loot
I think that this solution addresses every concern people have been having in this thread:
-don't add statuette/other extra rewards as it would hurt the economy
-make pking more profitable since it requires greater amount of risk depending on your level
-gives an incentive, although not extra reward, to use BH as opposed to regular PKing
-Encourages players that rarely go pking to try their luck
also by asking for a minimum risk it would also encourage lower level mains (lvl 80-100) to go pking since the players they would fight would have a similar risk because as it is right now, a lvl 80 "main" is going to be risking alot more than a lvl 80 pure normally (full rune/d legs as opposed to blk dhide chaps, climbing boots, etc)
Personally i'd favor BH over regular wildy if i was guaranteed that the people i would fight would risk 200k+
