Agree, even tho they reduced the cost, the fact that it requires KBs comes with major problems:
1- It's very frustating and unfun for healers to get it.
2- No point in grouping, since it's a competition for who gets the KB
3- In an area with lots of elite monsters, it's not uncommon to lose your bloody coins to those elite creatures.
Really disliked the world pvp featured in 5.4. Add that painfull grind to the fact that PvE gear is better in world pvp, and the fact that it has a 10 min cooldown, it makes one of the worst grinds in WoW.
Before 5.4 came out, I was looking foward to the world pvp system in 5.4. After 12 bloody coins, I'm already burned out and left the island for good. Like, half of the 5.4 content already burned me out, nice hum?
