Playing alts kinda sucks

I really like this game and it great for my main to level 90 running t16 when I have them if not t15s corrupted and if I have to t14. I really enjoy playing alts in other games because I like to twink my alts gear them up and blast content. But with this game you can twink your toons it all good. The bosses how ever are really over powered even with a twink. And also I don't feel like I am blasting just more powerful
