I am a lone wolf.
Good
I liked the story and look and feel of the missions and also of the jungle environment.
5.56 vs CSAT ballistic protection was quite challenging. But hey you play Arma 3 to have a challenge.
If you select Recon Sharpshooter you have no proper stealth nor ballistic protection, but a 7.62 NATO fire power or you select a Assault Class and you have proper stealth and ballistic protection, but a 5.56 potato fire power. Most of the time was Recon Sharpshooter with silencer.
I would have been happy with a MX with 6.5 as in all NATO missions before.
In jungle environment firepower and penetration is important because of the many obstacle. To get a critical it is with 5.56 way more difficult.
Even Syndikat has more fire and penetration power with the 7.62 AK.
Bad
I don't liked that you cannot pause or safe in Solo.
To Improve
Plain class selection for an Elite Unit is quite unsatisfactory. Some equipment customization would be cool.
I want to see more of Tanoa without third party content (because this content is mostly modded).
I want a follow up. This was quite to short. Yes, in terms of story line I am greedy.
