With every level, the amount of xp needed to progress to the next, increases. You definitely feel it after level 75. If all goes well, I should have enough to buy a pack tomorrow. So hard to resist even though waiting for 100,000 starbits is probably the right thing to do.
I played less than usual yesterday and the drop in ranks only went to 447 instead of the usual 480 to 490. Maybe this is the unique card count working its magic or maybe there is a delay in the effect of the rankings.
Ego is definitely on the way up and has now crossed the 20% mark with the drunks. Probably after the next pack, I will go do music lessons till level 85. Speed things up a bit and unlock the next mission.
