Same goes to me and everyone in my server also.. seems like after the 4.0 update, too less level 5 rune appear from 500 keys draw..as from what i can see, from 500 draw, only 2 lvl 5 runes will appeared..so i'm also asking the oasis is dis a bug or is it the new cave key draw system after 4.0? I hope moderator can answer for this question. Thank you.
