Because the good majority of them are controlled by shitty players who suck at strategy and have no idea how to properly use the original supers for them. People follow trends, if they notice less people are running Titans because of various, unfounded reasons, more and more people will stop running titan as well, leading to a rapid decline in Titan presence on the leaderboards. To be specific, I don't necessarily want it "nerfed" I know I used the word but it's only because it's an easy word to use that everyone understands; Change. It really only needs minor tuning. I have 4 suggestions, and only a single on of them need be done to perfectly balance it and bring it back into line with all the other supers.
