This all depends by how they define ''acceptable'' latency aka how low is the latency bar set.
If it's down to red bar... well, that's bad, since by fact, yellow bar in Trials means a lot (it is really bad and severely affects gameplay).
Not a fan of this change, not only due to lag (it can be just worse - mathematically), but also due to the fact i mentioned above, that if you are unlucky, you might get super hard teams multiple times, one due to RNG, one ''guaranteed'' due to the high wins change. While the idea itself is ok (making flawless more valuable and sweaty), not sure that the goal will be met in practice (due to RNG).
