The ability to proc it with her E made it take no skill to proc her Q. R did all the work of getting you in range. Why may as well just let R proc it in that case.
It does take more skill to proc that Q as you also have to be able to work around the enemy being able to avoid it. Be it by throwing your W on top of them so they can't move away as fast, or using R quick enough that you can proc it before Q's cooldown is back. There is a skill difference. Has nothing to do with bias or "academic" views. Being able to orb walk as a melee is just as important as it is to a ranged. Being able to stay on your target while continuing to AA is a skill based mechanic of the game.
Her reliability of her damage and the range she can preform it were a problem. This problem started when they made her E able to proc Q. There were many Akali mains who wanted this change gone before they changed anything else about her.
Trinkets offer true sight in two ways. One is a 2 minute cooldown that drops a pink ward. The other grants the user their own Oracle Elixir effect. Meaning they have to be in her W to show her. What this means is that nothing actually changed. Before the vision changes(S3) you could buy an Oracle Elixir(usually support or a tank had this already) and it wasn't rare to spam pink wards all over the map. While their availability is higher(free trinkets vs must purchace), the usability is lower(cooldowns, durations). The actual vision options to face her have not weakened. They just work a little different.
And what do you mean Nid lost power to gain her ability to jungle? She gave up nothing for that. She'll stay toxic her current state until they give a form of counterplay to her Hunter debuff. And "dodge the neverending spear spam" is not counterplay. It gives her a 750 range targeted gap closer that she can follow up with a lot of burst. After the spear itself already did damage. I would agree that it is a good change for the jungle in general. Being that it's in such a poor state, just gaining one more viable choice is a good change. Toxic or not.
While the E change did help her lack of counterplay beyond "beat her up before 6". I don't think it fixes the real problem with her.
R is still powerful as hell and she will kill almost whoever she pleases with it.
Give R the Yasou dash treatment. Making it so you cannot dash the same target within X seconds.
Make procing her Q remove this timer.
Revert the old Q damage shift, allowing her to farm easier.
If this proves too much of a nerf to her ability to stay on a target. Consider undoing the R cooldown change they did.
Honestly undo all the nerfs they gave her back in S3 and do the R change and she'd probably be in a good spot.
