That was faster than expected and I have now brought down the ego to 0%. Hopefully with more skill being added with every music lesson, this will make getting drunk fans a bonus when doing missions.
From a levelling up perspective, I am currently midway through level 53. I should be able to hit level 54 by tomorrow if nothing crops up and then maybe two more days to level 55. So if all goes to plan, it should be level 55 by Sunday.
The tradeoff when it comes to doing lessons over missions is that the pack buying has slowed down a little. Starting to feel the itch to buy more packs already.
Looking at how 0 ego has helped, the max per mission for me now is around 3,000 Starbits. So it should be quicker to get to packs since I can still only do 2 missions per day.
