I mean...they really weren't. The only reason that class may feel so weak to you, is because they were so ridiculously powerful before. Sun breakers were game breaking, not being able to one shot them to the face with something like stillpiercer or the 1k stare was a little overboard. Titans get several hammers that can track and explode, and hunters get 3 shots that do neither (not that GG is weak, it's perfect). I suggest using striker if you want to feel powerful, or defender if you're a more skilled player. Defender is easily the best Titan subclass and certainly the most respectable one.
I havent even finished breaker lol. I mainly use defender and striker. But warlocks my main. I'm going off of what i experianced in pvp going up against them mostly.
I sincerely believe they have been over nerfed. The armor and coscate (or whatever its called) are fine wjere tjey are at now, but why was blast radeus nerfed?
Noooooo, I would never have known about a perk I have equipped on my hunter, which is my main. HoS gets an explosion without perks. If you break it down, HoS and GG are essentially the same, the differences being: GG is always accurate and has solid range, HoS can track and explode early, HoS has several hammers before the super ends, GG has 3 shots (+1 with helmet) and lasts a very short amount of time, HoS can regen health, GG can cause enemies to explode AFTER a kill.
GG and hammers are fine, add in all the abilities Titans can run with hammers and the class is perfectly balanced.
Edit: Almost forgot about the perk that grants Titans a bonus to agility while standing in the flames of hammers.
