Idk if you knew this but, they can shoot back lol. If a titan is running an over shield, your ttk is nothing compared to what the titan is about to have on you. Your only counter is a special weapon. As for the hunter, it comes down to how they use it. A stupid hunter will go invisible and peek instantly only to be killed, a real hunter will wait 2-3 seconds to completely be invisible to enemy radar and attack from above or slide and rush with a chaperone. Either one is hard to counter if you have no actual idea where they are, if the hunter tosses a smoke grenade to throw you off then its GG, your only counter at that point is to run away. Reminds of me how annoying it was to counter shatter dive back in the day you remember? When the only counter was running away? Lol balanced!
Best advice I can give because I’m just a blink warlock since D1 😅 80% if the pvp community does not know how to react to it anymore. I usually throw my melee than blink over the barrier to re-melee them into the orb or throw my grenade behind them and than melee Or just wait for them to be dumb enough to peek out. However, Hunters need a longer cool down with inviz. If I can’t blink 24/7 anymore, they shouldn’t be able to go invisible 24/7. I played halo back in the day I can see inviz with no problem so I really don’t have a problem with it.
