This may seem stupid, but I've been a level 50 miner for quite some time and regularly gather mats in Northern Thanalan, one of the level 50 nodes gave an extra shot if strength was greater than 202. I've always had the extra shot, until today...

when I look now my strength is 200, is there a factor in game that affects your strength that I've over looked or has there been a change to node requirements that I've missed?
