Given that SMN had such a general lead in all content at all percentiles and not just TEA (recall a long thread I posted where we brought up the fact that this would happen, and that RDM would need buffs), it comes to no surprise that they opted for one of the easier baseline adjustments, just like all the previous times they adjusted DoT potency up increasing the baseline damage in a similar fashion.
Whether it manifested through DoTs being changed to 40 (-~3%) or 45p (-~1.5%) each or reducing pet potency across the board (which would have further ramifications and wouldn't be as elegant), they are one of the outcomes we were expecting. 40p would fit the bill for the meme.
I do not agree with the notion that removing TriD resets is the solution at all and if anything tells of a lack of foresight with what would happen in typical play in practice with the current job structure and fight alignment. It's asking for steps backwards in flexibility which is not what we need to see happen again while simultaneously being a bigger potency nerf from the extra hardcast GCDs that would have to happen and the lack of on-hit damage. It was a completely different matter back in HW when we did have a separated cooldown that did not reset with the 1 DWT aligned TriD/min with 3 different DoT timers and Contagion to add 15s to them all. The context has shifted tremendously since then.
