gambit will definitely not be there as an org, but maybe the full roster and the coaching staff are hired in another ''not too good team'' that should be in the league. For example, navi should be there as representatives of the CIS region, but most likely they will hire the gambit roster.
Also, the same will happen with acend, or at least i think so. I think that rito games will want to have 1 team from each 'subregion' (vrls) so there will possibly be a team from mena. As teams in mena are not that good rn, (there isnt any mena team in vct) they might get the acend roster.
Regarding of a spanish team, i think riot could take mad(rid) lions as a spanish team, so they dont pick up a team from the vrl, but i honestly think that would be a mistake. I think from the spanish vrl they should take either koi (not very likely since their level rn is quite bad, 2-10 in the vrl), giants (the most powerful roster in the league, even if they arent winning (7-5, 4th) ), or heretics, which would be a good option, but im not really sure about this, as they arent performing too good in the vrl (6-6). If i had to bet on something, i would bet they get giants or mad lions.
Also, G2, fnatic and liquid will be in the franchise league 100% if not, theyre trolling, and im not 100% sure about vitality, because they got into valorant earlier this year, not from the beggining, which suposedly riot was going to have into account, but i think they will get in as well due to the super roster they have.
