Is this season ending soon too?

I managed to get SSS rating again this season, so I'm wondering if I should start saving up enhancement materials. Most of the friends I used to play with have stopped logging in, so it's not as fun anymore. All the gear I got from drops was suited for Knights, and since my friends were different classes, I played Knight to maintain balance... but maybe I should switch back to my preferred staff-wielding class. It was most fun when we formed a 4-person party with 4 different classes, all around the same power level. I wonder if that will ever happen again.
