Personally I use every class and the one that aggravates the most is the Titan it has the Lightning grenade wich is a 2 shot and stays for a long time, it has shoulder charge a one shot punch, and last but not least the freaking atom nuke of the Titan slam I've been touching the top of the roof when I see someone Titan slam instantly I will die that thing has unbelievable range and it can stay for forever I find myself rage quitting because of that class. In the beta it was the warlock that was top of the guardians at the release of the game it was the hunters but now it's just flipping annoying as all get out I can't play crucible until they patch the class.
