Marvel Contest of Grinding

Is it just me or are the solo special solo events for this month nothing more than a long grind just to keep you in game. A total of 500 arena fights for World’s end?

I think these events should be less tedious overall. The entire drive of arena is a life-suck. I'm sure the guys who get the top 5-6* rewards are satisfied, but at what cost - sitting in your room all day avoiding life or risking your account if you are one of the ones who have driven up the demand for time using bots?
However...
If you do 10 rounds a day (30 fights), it takes like 10 minutes, which isn't bad and it helps get some of the other 1 and 3 day events moving along too. Arena suck for me - period. But if you break it up into small, daily chunks, it's really not that bad, especially for those who do end up getting a 5* (and a good one). Why anyone would rush this event in 1-2 days, I don't understand, knowing that the results may be less than stellar.
all milestones in the 4 star arena are 150 rounds x 3 fights = 4500 points.
