Has Er Gen's writing style changed in quality for the worse?

I'm reading AWE right now, does Bai Xiaochun stop being a coward and matures? Cause I'm at chapter 200+ and it getting annoying with the comedy, at first I was okay with it, but now it too much, I can't stand bai xiaochun anymore, cause if this continues and he doesn't stop and matures, I might have to drop it. 

Don't get me started on the armies of peanut gallery fodder and idiots in these settings. Im already glad if the MC has a brain. If his enemies are competent as well it gets that much better. But here is the thing: To write an intelligent character you have to be smart yourself, or invest exponential amounts of time and effort (But effort won't carry this on its own. Irrational authors can't write rational characters). If you are that smart you have an engineering degree and earn more cash that way. Understanding the profoundities of the world, my ass. Half of them wouldn't be able to do simple algebra. And the other half would fail the moment they attempted slightly advanced physics. 

Apparently you did not judge that it is trash but you called it trash. You also called WoC trash but you only read it for 5 chapters.

Maybe it's just me but I don't think using the excuse of being "example" would grant you a pass on saying something is trash. 

My issue with revisiting worlds is that the author broke the rule that he said could not be broken. It's annoying
I need the correct something. Webnovel authors sometimes have PhDs in engineering.  Writing webnovels just pays better than working as a professor 

Yes he remains that way. 

I can't say anything about his novels in general, but I don't feel that ISSTH was consistent in quality even within itself.
I definitely enjoyed the first 400 chapters or so to varying degrees, but the following 600 chapters was increasingly dreary and unfunny until I dropped it around the 1000chapter mark, I have no idea if it improved after that but I'm not really interested in finding out.
It has the same problem as many other cultivation stories where new characters keep being introduced and only remain relevant to the plot for maybe an arc or two at the most yet expecting the reader to care about them.
The same jokes kept being reused over and over until they became annoying, the fights became increasingly drawn out and boring, the powerups increasingly lazy to the point that the author just straight up invoked the plot armor for no reason other than letting the mc power up by being suicidal.
And worst of all, the damned rapist parrot just wouldn't go away.
And yes I'm a bit salty about this novel. lol 

Xianxia as a genre is not a fault, but also not perfect, just like any other genre.

Immortality - Long life span. So, what? Secondary can be a genius or an old man that lived for a long time. There is no needed to let the protagonist be the only one who can be unique. Or, just use the theme to play with the age-old question of "Is immortality worth it?".
Fast growth - This one I agree, fast growth is hard to make, but it is not impossible to have a consistent cast. Why can't the secondary be as extraordinary as the MC?
Multiple worlds - This one is the same as fast growth. Plus revisiting the old ones, and bonus with the ponder about immortality. ( When all your loved ones died off. )
Survival of the Fittest - Why can't the secondary be good, just not as good as the MC? It's not like everyone would die if they are a little weaker than others.

And finally, authors are free to change the secondary cast, as many times as he wanted. Good stories didn't need an unchanged secondary cast. 

In my opinion, Renegade Immortal is currently still his best novel.
