Since the only thing that change with the tier is the loot speed ( T1 to T4/T5 = 1 loot every : 4.40s / 4s / 3.30s / 1.87s ), if you can have at least 5 pets T4 it would be the best obviously, But in the end, if you don't have 5 pets that high yet (you will eventually, the game is generous now), it all depends on how fast you are able to clear the packs of mobs, you may not need pets of a tier that high if you are slower, I can't give you a straight answer to that
Great choice, I hope you will like it 😄 If you ever need some info about the class you could check out @Jonlaw98 and @NotTheWorstt on RU-vid, they both main DK and have great guides about addons/crystals/skill rotation... I often check out their videos :) And of course the Dark Knight discord server discord.gg/C3UFPub2yW ;)
