Blue NPC Resists

[RaldoMcdaldo]

Just curious, not a complaint - I've been experiencing higher than normal (normal being throughout 24 levels with a Troll Shaman) spell resists with blue mobs since the patch. I figure roughly I am being resisted at about 30% generally, all blue mobs, and certain blue mobs resist certain spells repeatedly until my mana is gone - some cases up to 6 times or more in a row with the same spell. The later described chronic example happens every three to four blue mobs. This was not the case, before the patch.
Am I unique or has someone else experienced this problem?
Thanks for any insight.
