SE, don't nerf SMN's DoT potency. Remove Tri-Disaster's Reset Mechanic First.

Summoner's problem is never its DoT damage at the start of expansions. The problem is that each expansion they take hard 90 degree turns in the Job's design and flow. Go back through and look through Stormblood patch notes.

At no point was DoT damage ever increased. From the start of Stormblood to the end, the rank 3 dots were 50, which at the time was mostly equivalent to what Summoners had in Heavensward with Bio + Bio II + Miasma I.

This is not correct at all. There's a reason why the DoT yoyo meme exists with 40 50 40 50 x.

Stormblood DoTs started at 40p/t each. In 4.06 they were both increased to 50p/t each due to Summoner's weaker damage at the time, all before the huge patch that was 4.10.
