It's more likely to be 240 given the past expansions.Expect a soft cap at 230. A hard cap won't happen. The hard cap will be the level at which you can no longer get xp on a lvl ~230 mob.
They just need to add more parallel content. One of the reasons i do like the game is it takes some effort to get to end levels instead of some games where it can be done in a few days with experience and help. By making it more difficult you keep out more riff raff (yes you know who you are

If you want to avoid paying OTM perhaps invest in a few devices. You can sell them easy and get most of your money back if you get bored or change your mind. I've never paid more than 10 usd total and yet have solod the 200 5* along with 6* dl bosses. Tbh most people who pay huge sums of real money cant do that.
Farming items is one of the few activities in the game it strikes me as odd how many people dont like it and would rather pay real money to make it come easy.
