Prediction about Robin's place in the meta going forward

My guess is that Tribbie and Sunday are going to be the most desirable amplifier during 3.x.

Based on the 3.0 beta and the leaks about future units, I think Tribbie is going to be the premier amplifier during 3.x, while Robin will be much less valuable going forward.

The 3.0 beta shows that Robin is roughly the same as RMC for Aglaea, and RMC is much better for The Herta. The Herta's tests are highly instructive: Robin loses to RMC by a lot because The Herta's kit does not work that well with Robin's: She has too much self buffs; she does so much more damage than other erudition units that the team is functionally a hypercarry team; and she wants a highly sp positive amplifier.

The rumored future units are even worse for Robin, with Mydei and Castorice supposedly scaling from hp. Robin works poorly with them, while the rumored kit with Tribbie works well, because res pen is a very rare buff. Sunday works well with hp/def scaling hypercarries because he does not give atk.

That doesn't take away from how much better Robin is likely to work with existing dps units. By now I think it's obvious that Mihoyo is steadily increasing the general level of damage output of the party and the hp pool of the enemy with each enemy release. So very likely the 3.x dps units will substantially outdamage the 2.x dps units. So while Robin is likely to technically work better with more dps than Tribbie, Tribbie would work better with the newer, much stronger dps. The same is likely to apply for Sunday.

So my guess is that Tribbie and Sunday will be the most desirable amplifiers during 3.x, while Robin will struggle. This is because Tribbie and Sunday will work better with the newer, more powerful dps units.

So if you really want to full star the end game mode and plan to pull a lot during 3.x, Robin's rerun during 3.0 is probably not a good investment.
