After the nerf it's easier to counter but the issue is both Bubble and Well are designed in pvp to control a single spot this gives an advantage. However I wouldn't worry too much as it sounds like bungie plans to rework bubble and well probably into the ground.
That's one of the things I have a hard time believing would be in the game for this long even though the people it's like that for have no idea why it's like it is.
Literally everyone hates the way it's set up in trials but it stays like that. It's like that mostly so casualer players can have more of a chance. It's also possible evidence of the power of certain cabals within the company that it would be such a titany experience.
I wonder why there’s so many titan bubbles (and well warlocks)… it’s almost like forcing zone captures had something to do with it. But yes, implicate the class that continues to receive nerfs due to choices made by Bungie. Bubble already got nerfed after the first new iron banner mode and again now this season. Instead of addressing the root of the issue, blame titans.
