I'm a casual player and decided to take advantage of this nice server-wide xp boost and started a cosmic prestige on my Spider-Man today. And by casual I mean that I've been playing since the beta and have just over 19 days total on my account. Because of this I always avoided the though of actually cosmicing, especially since the I wouldn't want to do it on my main Black Widow, but when I got Spidey 2 days ago and saw how fast I got to 60 I decided to just go all the way and see what it's like.
First thing I noticed is that the grind is definitely as real as everyone warns about. The raft would normally get me to level 10 with the server-side bonus but only just got me over level 3. I have a few xp boosts from events that I've been hanging onto that I may be able to pop for a few hours of a pretty large boost, so hopefully I won't get stuck in the high lvl 50s without anymore boosts once this server-side bonus dissipates. Also does anybody have any tips for in-game achievements or such that I could pick up along the way that'll make my grind seem a bit less grindy? Like focusing on a particular enemy type or zone to farm in outside of my inevitable MM grind?
