With all due respect I would suggest you to put side by side your comment and my lengthy reply / analysis that addresses all of the points in bold from your post.
The only difference so far between our viewpoints seem to be the fact that:
- you take Master/Pred legend pick rate as basis to prove that in this case Ash is unbalanced
- me putting Masters/Preds into the same category as blunt hackers that make any legend unbalanced = data not representable
Rest is up for debate of what is possible what not regarding developers meeting or not meeting requirements from the player base. Imo given above said they actually do meet quite a lot of what is being asked for by the community part that spends money on the game = lazy, mostly controller players, that play casually and want "run and gun" type of experience are getting 2/3 of suitable legends to do that with additional bonus of some of them being unbalanced to make things even easier in terms of achieving "run and gun" results.
To back this up I will make a prediction that now Vantage despite getting major buffs - mobility and less noticeable ultimate - will be as "(un)popular" as Sparrow (being new legend and not reaching top 1 or 2 pick at least for the first split after being introduced) just because of the fact that Vantage is more MNK tailored legend = minority of player base => that will result in mediocre increase in her pickrate.
