My guess would be handheld mode.

In this mode Switch throttles down to be effectively something similar to WiiU - if it was only docked mode AAA publishers would most likely put more effort into making ports for Switch, but handheld mode seems really painful - even Nintendo had to do some not so great compromises on Odyssey for it.

But who knows, if Wii had CoDs, maybe Switch will have those big mainstream AAA games as well.

It's also important to remember that publishers follow profits, not specs. If the Switch provides an opportunity, they'll jump at the chance, even if it seems impossible. If the Switch can run a scaled-back version of Doom, then it can run many other PS4 and Xbox One titles.

cuz it takes time to make games. Third parties weren't sure how the Switch would do after the Wii U failure, so most of them probably had nothing in the works for the Switch when it launched. Despite this the Switch managed to get some older ports of popular games already. It would probably take a lot of effort for games that were built to push ps4/xbone to be ported to the switch, so instead we're getting older ports. I'm sure a lot of games got started for Switch in 2017, by late 2018 and in 2019 there will probably be strong third party support for the Switch, including new AAA games built for it, not just crappy C-team ports of games like Nintendo owners have gotten used to since the Wii. So far its pretty much indie games plus Nintendo's big hitters that have driven the Switch. But within a year AAA third party support should start hitting and helping to drive Switch success.

It doesn’t deserve them. Just wait for the cliff drop of sales. Also only nintendo games will sell

As much as I love the Switch, it can't run some of those games. A poor port just makes the Switch look bad in the eyes of the public. Better to not have a game at all than to have a horrible version, I'm my opinion.

I do want Rise of the Tomb Raider on Switch, though. It looks just fine on Xbox 360.

I guess I should have specified Western third parties. Going by VGChartz

Lego sold better, but it was originally a Wii U exclusive, so that's more or less expected plus Lego usually sell pretty decently on Nintendo hardware, likely due to the younger demographics. I don't really have many other good examples for comparison considering that most western third party games on Switch so far are late ports, so direct comparison is unfair. Going by the games that you mentioned (and some other late ports):

Now are these most of these bad figures? I wouldn't say they are, but beyond L.A. Noire (for some reason), all of them are unquestionably lower than XB1/PS4. Now is that fair, considering the Switch's significantly lower install base? Again, not particularly. Still the point remains that major third party games sell less on Nintendo hardware.

As for the developers touting high sales on Switch? Those are almost universally indies. You see Team Meat and Team17 happy. Do you see Bethesda touting how successful Doom or Skyrim was? EA with FIFA? No, because they weren't impressive. I want to be crystal clear. I do not think that indies are lesser. I do not think they are not important. They aren't lesser and they are important. HOWEVER, indies need lower numbers for the Switch to outsell other consoles, something that is greatly helped by the lower quantity of games on the platform. An indie selling 10k is a success, 100k massive, 1m unthinkable. But EA, Ubisoft, Square Enix, etc? Needs more than that.

All of this is on top of what many others here have said, that porting to the Switch takes time. If a game started development in 2015/16 for release in 2017/18, most AAA's literally CAN'T have a Switch version ready around launch. 

Switch will never be able to run quite a few AAA console games so the vast majority of 3rd parties are just content by picking low hanging fruits on the Switch such as porting last gen titles and much less technically proficient games ...

As had already been said, most third parties probably expected Switch to flop after the Wii U, so they would've adopted a wait and see attitude. By late last year it became clear the system was set for success, but any games started then won't be ready yet.

To be fair, neither the 1080p nor the 60fps are locked on PS4, and on Xbox One the resolution drops to around "828p or lower" and the framerate into the 40s, so it's not like the game isn't demanding even on dedicated consoles.

Activision had a lot of success of the Wii; Skylanders, Goldeneye 007, COD3/W@W/MW/BO...
