I don't know why people keep saying they don't like the new loot system of WB. The new system maybe piss you off but it's totally addictive. This last year we've seen how the usual server activity almost disappear during the WB week. People keep hunting the WB hoping they will get something different than a useless potion next time. Even if the fight and the waiting are boring as hel or they can't finish 2 combos because the lack of FPS or the lag, people keep hunting the WB. I think it's clear the reason for this compulsive attraction for the World boss is the loot system. It's a bit of compulsive gambling I suppose.
The MMOs are for sick people like us they are build over compulsive collecting, compulsive gambling, achievement delusions, masochism,... So don't ask for a pleasant loot system. We will get exactly what we are paying for.
Thank you Funcom, I'll be the first of the line to get intoxication potions or rabbit pets from T5 loot chests.
