My glory was getting real low recently. I like to maintain ~2500, because some weeks I need to by a LOT of the troop packs. But I've gone to nearly 0 the past couple weeks, so it was time for some focused glory-generation!
To start, I used about 350 glory keys I had stockpiled, along with about 300 gold keys I purchased. The keys alone generated just under 400 glory for me. (Plus lots of souls, as I mostly disenchant everything for souls these days.)
Then I played some PvP - earned about 130 glory over the course of an hour or two of casual play.
Then I buckled down and did 40 maps. That was a few hours work - broken up by other tasks periodically - but at the end those maps earned me a total of 1470 glory.
So my total glory gain today was 2000. Not bad!
