BTW, if curious the Canon EF 24-70mm f/2.8L II USM Lens is my most favorite and most used lens.
If I were in your position with a significant investment in EF mount, I might give thought to buying a second one while they last.
"I would recommend that you send your lens to ... Canon ... repair facility to have it thoroughly checked out."
That is your first course of action. The lens is very much likely to need, at the minimum, realignment after the fall. Obvious damage not being noticeable but internal damage is possible.
"It is time for me to get another primary camera."
Best choice staying with EF lens mount would be a 90D. However, this is the age of mirrorless so buying a new DSLR is not the best practice solution. The future is mirrorless not EF. It is possible to adapt your 70-200mm to mirrorless cameras.
I, too, am concerned about DSLR v. mirrorless and am equally certain the future is mirrorless. It seems my best course of action is to continue to shoot my camera, see if I can ge the lens tightened up, and wait patiently for the new Canon mirrorless camera rumored to come out this year... right?
"... the new Canon mirrorless camera rumored to come out this year... right?"
There is already some very fine mirrorless Canon cameras on the market. There has been for some time now. The missing link is a full on pro model. The R1 for instance and it will cost somewhere in the $6000 range, body only!
