The only thing the tag games have are openings and endings, there is no story mode at all in these, what contradictions you gonna have from them huh?
Never said all endings in them are canon, as much as not all endings in the main games are either, not hard to see which are fine for use and which arent, in T7 they shows few scenes from the tag games that they have, as well as they do for the main games the same in the flashbacks, meaning tag 1 and 2 are part of the canon (with what can be counted for the series), if you cant even understand that i dont have anything else to how stubborn you are on this head canon of yours
Kage, Gill, Akuma appeared in SF5 as DLC with their own story in this installment, you will claim them non canon cuz they are DLC? Julia story says her deal in T7, as much any character in the game, its no different from Paul, Bob or Yoshimitsu story in the game, Anna story ties with Nina, you will say its non canon too just cuz she was added later as new content?
DLC=/=non canon and guest characters(except Akuma) are never considered canon, they are guests for a reason, they dont change or have any deal with the series they get in, not only you compare two entirely different things(a legacy character and guest one) you also insist strictly on your own personal opinion that she shouldnt count just cuz you say so
What ifs are the characters that arent present during the intervals of games or which are dead, clearly you didnt read at all, even then, Ogre ending in tag 2 shows him causing destruction what its contradicting here?it doesnt say he is alive beyond T3 or affects anything in the lore its just him destroying stuff there, thats all in it, no different then Feng ending in T6 where he destroys a ball of lava, it affects anything?No
The temple crumbled down after the Jin killed Azazel, Dragunov in his ending shows the temple still intact, also whats proof to say his body was still intact afterwards?None at all, his ending implies he beat him which didnt happen and Raven when he arrives and finds Jin body, there is no temple anymore, you will tell me he somehow got to Dragunov after there is nothing left? In T7 we even see Raven with Jin body there in the story nowhere implies he got hurt by Dragunov
