I mean, there shouldn't be any IF fan out there nowadays expecting anything that sounds like their 1994-2008 catalogue. Jesper leaving removed a critical component that can't be replaced. Anybody still listening to the band expecting anything resembling Lunar Strain - ASOP needs to move on. That band is gone.
Anything after that is realistic to expect, just because the main songwriter, Bjorn, is still the main songwriter. He could write another SOAPF, another Siren Charms, another Battles, another ITM, if he wanted to. Granted Battles and ITM had heavy involvement from Benson and his crew, but the band are still working with those people, so, still not unrealistic as an expectation. With that said IF have been going off in different directions since Clayman at this point. No album since then really sounds hugely like any of the ones that preceeded it (imo), so you pretty much have to assume a new IF album isn't really going to sound much like anything they've done previously. Some would see that as a positive, some as a negative, but it is what it is.
There's no way IF could have kept releasing Colony/Clayman style albums to the present day without a drop in quality. There's only so many ways to evolve that sound, and Jesper/Bjorn were already tired of it by 2000, meaning they'd be forcing themselves to write the material and that kind of situation never leads to anything good. The music would just have become derivitive and pointless. What's frustrating from my point of view is that they never really settled on a sound or style post-Clayman. Every album was a new direction, with constant experimentation on production. The band had zero consistency when it came to how their output sounded after leaving Nordstrom, and whilst in some ways it makes them very interesting to follow, in other ways it's irritating never knowing what to expect and has contributed to the fanbase repeatedly splitting as time goes on. There are very few fanbases out their as fractured as In Flames' fanbase, and this is in large part down to how erratic and unpredictable their musical direction has been over the past 20 years or so.
As far as what I'd
want to see as an IF setlist, as opposed to what would be realistic... not in order of being played, but in order of albums:
Behind Space
Upon an Oaken Throne
Stand Ablaze
Lord Hypnos
The Jester Race
Jotun
Jester Script Transfigured
Episode 666
Embody the Invisible
Zombie Inc
Only For the Weak
... As the Future Repeats Today
Satellites & Astronauts
System
Minus
Evil in a Closet
Dead End (or Crawl Through Knives if Lisa wasn't available
)
Vanishing Light
SOAPF
Fear is the Weakness
If that was the setlist I'd literally love every single song played. I could swap a number of songs from the old albums in and out though, especially from TJR/Whoracle/Colony/Clayman. I'd be happy with practically any song played off those albums, and most of the songs off Reroute as well.
I wouldn't want anything after 2011. Not to say some of those songs don't sound decent live, but nothing they've done post-2011, in my mind, comes close to what they did during the 1994-2011 period.
sure they may be similar, but the riffs have a completely different structure, and it's in no way a rip-off.
I'm not trying to actually argue by the way, there's no malice in my words so please don't take it any other way than in jest
weird hill to die on, but to each their own I guess 
):
) the fact I've seen In Flames 5 times, 4 as headline, and haven't seen Only For The Weak since my first IF show in 2014 is actually ridiculous.
