There are around 10 basic types of goals that never happen PES anymore, Or very rarely vs AI
Chipped goals
Rounding the keeper
Nutmegging the gk
Drilled roof of the net
Most types of headers (Downward,Looping,Guided ..etc)
And many others
Okay, before I go any further don't take this as some confrontational reply. You can only comment on how you see it and I don't know how much PES 2017 you played or if you tried the beta for PES 2018.
Those bolded absolutely happen in PES 2018 and also in PES2017 against the AI. I know that having played six seasons of ML along with a fair amount of online play and other modes. Using Advanced Shooting, natch.
As for rounding the keeper, it is 100% in the game as I have seen it and experienced it in PES 2018. Can't say anything regards v. AI in PES2018, and it was rare in PES 2017, but other factors drove to that being the case.
I'm not sure if I would call nutmegging the keeper a cause for concern, but want it to be there. If it proves a rare occurrence I wouldn't then say it was completely ruining my enjoyment of the game in general. But yes, it should be there.
I'm not sure what you mean exactly by drilled roof of the net, so won't comment.
But placed, looping headers?...
Placed, downward headers?...
Those aren't exceptions either. Regards PES 2018, I don't think many nailed the heading, which is a good thing in some respects as it was too effective in PES 2017. I think everyone needs time with the game to truly see if it is nerfed or that there will be a skill to heading effectively in the game.
PES2017 had a fair share of variety in the kinds of headed goals you could score. PES 2017 also did possess more shot variety than people will give it credit for. A perfect amount? Nope, but there was variety or a perception of it being there.
I can only talk from my own experience, my own take, of PES in general of late. Below are three videos of goals and patterns of play from both PES 2017 (a stack of goals from over a season or two in my ML) and a quickly put together video of some PES2018 moments. I think it is the only way I can really project across my own experience. I'm not looking to prove anyone wrong or anything. It is purely the best example I can offer of my take, but even then it is just a sample of it over a season or so's play in ML and just few matches from the beta. I am not posting this claiming it as evidence of anything other than some of my experience.
There's an hours worth of viewing here; all using Advanced Shooting apart from a few Manual efforts. The first goal in the 2nd is a fine example of some of the types of trajectories and flights I experienced frequently. There is a fair few headers in those PES2017 as well, I believe. Like I say, I am not trying to submit it as evidence against yours or anybody else's claims. I'm not saying you or they are wrong, even if I myself don't agree...
