To be honest, what I started noticing was that some of the rewards you get along the way were far more valuable than the reward itself. Based on the last 2 events, however, even those rewards have now gotten lousy. Events are slowly becoming opportunities only for star chasersI simply refused to pay to finish from the get go. In my opinion this feature reduced the price of S-series planes it further meant that the only thing I need do is to just show up and I'm done... Whatever happened to the normal blood and sweat grind?
Currently my priorities have somehow shifted to "if I didn't go to level 20 through normal play - tough" but I lose no sleep about it.
