Yes my guild has done the same taken 2 lvl 4 npc's and we arn't getting a single buff. Just another lie by tynon and of course it isn't working, nothing is EVER working!
Hmm that's odd that you say nothing ever works because the first thing I noticed when my guild took a lvl 4 map was how my PStone jumped from slightly over 700k to over 1m. I also notice that for 1st place arena awards I get 2k rep instead of 1k.
