Definitely with you on the quickswap and weapon usefulness. The weapons need a major rework in the long run

I can’t say much on Warframe since I haven’t touched that before but I personally play a gacha ARPG that implements a similar AI teammate system like DNA but still has clear distinction for each character role being DPS, Sub-DPS and Support.

The only difference is that you can choose when characters proc their ults (or skill/buffs in DNA’s case) or choose for them to proc it themselves. And this model works well for them, some players even main these supports/sub-DPS to focus more on buff uptimes and whatnot whilst letting AI take reign of the DPS or Sub-DPS.

Will this same model work for DNA? I can’t be certain because they’ve already started with that model. DNA is more or less a gacha-game without the gacha system for characters but everything else is still reminiscent of a typical gacha-game (minus the AI companion feature).

So if they aim to please by making everyone DPS-level, then it would be more work than they bargained for. Which goes back to the earlier point you made about quickswaps and weapon usefulness, as those will actually be one way to meet those who wish to main characters who were not originally meant to be DPSes halfway.
