Higher Level Single Player Adventures

In may have already been suggested, but could Single Player Adventures higher than Level 7 be introduced

Why? What difference does it make whether an adventure is single player or not (ignoring co-op)?

Nothing stopping you from playing a adventure of a higher level than 7 and not inviting.

True..but my thoughts would be to associate with a quest chain. I'm assuming that like me adventure quests were completed by buying the loot spot long before being completed as an individual. Rather than exploiting this it would be good to do a adventure quest chain where you have full responsibility for completing. But that's just my view point.

I am a bit torn on this.

I enjoy selling lootspots, it's my primary source of income and maybe the only thing still making me play this game.

However, it would be good if there were single player adventures with comparable difficulty to Fairytales which would also offer comparable rewards - presuming that you get "loot slaves" which join, make kill & give you loot.
So, a decent solo adventure should have 3x as much loot for being exactly as difficult, but then only 1 player gets the loot (so the total loot coming into the game is the same).

Why? Because you can share Fairytales and rushing through an HLT with 3 maxed players (all having 2x MMA, Major and Cannons) takes less than 2 hours - while doing a solo adventure does not let you do that: you must wait for general recovery times and troops rebuilding.

There is also an advantage to Bluebyte in this:
A highly rewarding solo adventure is a reason for players to buy Premium.
If I do a Fairytale, I don't necessarily need Premium, as long as I can sell to 2 Premium players: I only lose about 10% of the total rewards by not having premium.
If I would do a Solo, I'd lose 33% of the total rewards, so I'm more incentivized to use Premium.

Indeed, we need some harder adventures to "force" lv50s to sacrifice and produce tougher troops (than R, M, B, LB and C). Of course combat buffs and MoMA will still cut down the losses, but that's just useful in a limited way.
Rewards could be grout and some new cool buildings (containing pop), but as in co-op adv...NO weapon.
