Just normal we did today 2 T1 Pops to T2. 1 was 5-10 kills and we got it the other one took us about 30-40 times <.< .. so it rly suxx sometimes, damn SE with his failrandom things w.
Took me a while too. Did it last night, spend 2 hours, pop's i'd say... 35 NM's before mine changed,, friend with me never got his to change.
Did as MNK/WAR + WHM/BLM, fought in pashow and jugner, fights were always pretty easy, the slimes in pashow would usually require a full heal after-wards, works were easy.
The easiest way I've found to get them to change is just take 2-3 friends out with you, then take turns popping the NM's. Since it doesn't matter who gets the kill, just who pops it, take turns popping until it changes. We did it this way and it took maybe an hour for all 6 of us.
i did close to 100 t1 with no change finally went back to the npc dropped my abyssite and got a new one. i have close to 10 lsmates that have done this with me all getting color change. ive tried solo duo trio still no change. Hoping the new abyssite makes a diff havnt tried yet. All i can say is stay at it even tho i'm frustrated enough to gm see if they can explain it even tho i know that wont get me anywhere. Good luck to you all hope your not stuck like me.
