Is Trouble viable into the late game?

Hi all, I love pet classes in games all the way back to WoW’s Hunter, and Trouble scratches that itch for me. But I see a lot of posts about how Trouble kind of sucks, how you need to put points into blue tree to get the minion buff which is largely wasted skill points, and so on. I’m level 25, and late game is still far away, but will my cute Trouble stay decent as the game gets harder?

I don’t care if it’s not top damage or anything, I just like pets, but I don’t want to have a useless action skill either! So should I keep on with Trouble or swap and get used to using the phase clones?

I do have the DLC and access to level 60 if the extra skill points matter a lot since game’s launch
