Does it really takes 100 hours to get from level 1 to level 110 ?

I see posts on reddit and other forums saying that it takes ~100 hours to max out the battle pass by just playing normally . you don't even need the extra xp bonus from the other legends .

is this really confirmed . atm I am level 7 and it seems to take forever to  level up and I am already got ~75k bonus xp from using 3 legends. 

also is it always 29,000 points per level or it going to increase once u reach top levels
