You should have no problems doing it, the current gear content allows you to overpower a lot of the bosses health. Certain fights can be tricky and mechanic based, you still have to watch where you're standing in Firefighter and Freya watch out for roots and inturrupts. Other than that, it's pretty straight DPS and awareness approach. Yogg+1 just watch out for Maladay, green beams and purple skull.
