I mean... doesn't obscuring the data just slow the problem at best? People will still do guides based on gut feeling, and their anecdotal evidence, even if they don't have 26000 games to back it up.
For instance, if starting with Noble 3, level 4, and a 2* unit, by the time you hit the first PvP round, leads to 78% of placing 4th and higher; I feel like at that point the issue isn't that people know going Noble first is better, it's that going Noble first is oppressive.
From my point of view, it'd be like hiding the upgraded items' effects until you complete them, since that way people build more diverse items. It creates a more diverse meta, but only until people figure out the hidden numbers.
