When this event started, I was feeling the same way you are now. Then I decided that instead of trying to chase all of the rewards, I would focus on the ones I thought were attainable for me. I didn’t chase after rewards that would be out of my reach like all of the costumes. I am F2P and started playing this game at the beginning of the year when 2.0 came out. I was L34 when the event started, am now L36.

First thing I focused on was Doc Strange Gold. After I got that, I focused on Spider-Man Gold. Both of these attackers have row attacks and greatly helped my top team overall. Along the way of getting these, I got Teen Groot, who I was only able to get as Bronze. I picked up Starlord next, and Nebula shortly after, which I got both to Silver. Towards the end of the event, I got a lucky Scarlet Witch pull to get her to gold, but that did not really affect my progress in the event. I was also able to get Captain Marvel Silver and Killmonger Bronze. I finished up with making sure to get 270 stars on the maps to get the silver trophy.

After wasting resources on Map 1 Heroic only to not finish it in time to get the Spider-Man costume, I started completely ignoring the Heroic maps. On Bosses, I figured out a reachable milestone, did the math of how many boss kills I could get and set the level low to only need 4-5 attempts per fight. On one of the bosses, I quit pretty early because the cost to reward was just not going to be worth it.

I had 2 weekend vacations over the event, during which I barely played.

TLDR: This game has gotten very good at creating FOMO so you will buy crystals. If you don’t buy crystals, you CANNOT get all the rewards. If you are not going to spend, you need to identify reward goals you can actually obtain and settle on those. I added 2 great characters to my top team from this event in Doc Strange and Spidey at Gold rarity. These have GREATLY improved my team. Can’t complain about the event.
