Make them ACTUAL treasure vaults.
Not a blinding display of colorful rainbows that reminds me all to much of the world inhabited by teletubbies.
Stumbling around I almost expect them to turn up ...man those things scare the hell out of me.
ANYWAY.
My suggestions for you are that you shrink them- cut the bs with all the coins scattered around- its a waste of time to get them all, precious little of which I have, and instead put down a few unique containers that drop pieces of gear for that tier of knight- or even rare materials.
Yeah, I don't care how low you have to make the chance of these treasure vaults actually coming up, but please make them happen.
The current treasure vaults don't fit the bill.
Thanks.
PS: OH and what the hell is up with putting down a sign of "Welcome to the treasure vault, relax you're SAFE here" and then place a few invisible virulisks that sneak up on you when you believe them, are you purposefully trolling players?
Sheet...
If you have so little time, what are you doing on a "MMORPG" where the primary factor is grinding?
You so 1337 you don't know the term 'grind'?
I give you 0, same amount of [redacteds] I give.
