Is it just me or am I leveling EXTREMELY slow?

Well, the speed that you are leveling at is absolutely nothing compared to what it was like years ago.
But I digress; I hate it when people say that sometimes! You are training at okay locations.. you probably just get bored with grinding, like me, and just see it as being extremely boring and slow. Sometimes I feel we are showered with 2x events and cards that stack (1.5x from recent events), that now, training on 1x seems as slow as like pineappleing molasses!!

Well, still. I've had enough of this the way how I level up WAY under average speed! I mean even in pre-BB I was under average getting a level 40 Assassin in about 2-3 months.

How many hours a day do you play, and how many do they?

I didn't ask them that but I would assume whatever an average person would do.

Also, I got to level 50 on a Luminous in 3 hours, with 24 Cygnus Blessing + 4 Att from Character card!!!
