I had over 700 points on the reward turn in NPC, is there anyway to redeem it now?
I was unable to log on the past couple of days
Nope - all points were needed to be turned in before the event ended.
I remember the first few ToTs, Doom and Sorc Dungeon. Not only were the points vendors up until the next one started, your points even rolled over to the next ToT and I think you could have well over 1000 (unless I'm crazy, I swore I had 2000+ at one point). I remember not even doing sorc dungeon because I had so many leftover points from Doom I could just claim what I wanted.
Ok, clearly rollover points was a mistake, but I see no harm in allowing the vendor to stay up for a little bit after the event, and furthermore, allow points to be still turned in too.
Unfortunately this is something they long ago decided against so nothing will change.
