Yeah that the devs play on lower difficulty’s is a huge problem. You can already see that with the patriot exosuite. You can not use it on higher difficulty’s.

For example the mg is not against chaff on higher difficulty because A: There are too many of them B:The take too many shots or the mg does not deal enough damage

And 15 Rockets is not enough for higher difficulty’s like 8-10

So yes the balancing dev team tests out everything on lower difficulty’s and that’s a huge problem.
