I submitted a response to the poll and read the results earlier today.
A lot of the questions were horrible, causing a lot of the information to be tainted in my opinion. I hope Respawn doesnt take it all to heart and make sweeping changes right away. I think there is some decent info in there but a lot is not. If Respawn wants this information they should do a poll themselves.
I'd wager Respawn will make changes based on the real-time data they're collecting rather than a particular Reddit survey. Any requested change would have to be as deafeningly unanimous as the complaints with the first tech test.
Honestly, when I'm playing Attrition, Bounty Hunt or Hard Point, I don't have much issue with the balance of the Titans. I use Ion mostly, and generally feel like if I play smart I can handle Tones and Legions fairly easily (good Ronins on the other hand, are the god damn devil).
But when you go into LTS, and it's ONLY teams of Legion and Tone, it's a problem... because it's fucking boring.
I'm not sure how to fix it though. Maybe make the clip in Tone's 40mm shallower. Essentially, only exactly the number of shots necessary to take out a Titan per clip. That way, you punish her for missing a single shot (or firing one into a shield, etc). Maybe also lower the aim assist on that particular weapon as well, force players to actually place their shots if they want the benefit.
As far as Legion, I don't know. I never use him. Maybe a slightly longer spin-up speed on his chaingun before the bullets start flying, and more spread so that fewer shots actually land as crits (outside his core ability, obviously)?
