I certainly don't have any illusion regarding Wenger.
I got the impression you were alluding to individual player development, which is where I disagree. I don't just want to deride Wenger even though I want him gone now, right now.
It's convenient to not credit Wenger for Ramsey's form but discredit him for his drop in performance since. Wenger is accountable, hence should also get credit.
Also, we have seen teams go through seasons and win Championships whilst collecting points disproportionate to their performances. I think it's unfair to assume we would have lost the plot anyways even if corrective measures to aide the squad were taken at the right time.
Anyways, I don't intend to change this into a Wenger thread. Just that I thought is harsh to accuse Wenger of being detrimental to an individual's development, despite the last 3 seasons. The team's yes, not necessarily individual's, in my opinion anyway.
