TLDR: Apparently Paladins makes some good sentinels and IGLs.
The Paladins pro scene was dying as Valorant started to take off. Most of the top pros especially in the dominant EU region went elsewhere but a couple paladins pros have stuck at the tier 1 ish level. Its a shame that the original NIP paladins roster never actually got to play together since I think their chemistry could have made them good in the early days even though I doubt they would still be unchanged today.
There are 5 pros who have been consistently signed to teams in Valorant. There were a couple others in NA and OCE that I used to see, but they don't appear to still be playing since the number of tournaments dropped with the introduction of VCT.
Bonkar (EU): IGL, Sova, sentinel, support flex: Played main Frontline(tank) in paladins after switching off flank Formerly of NIP, BONK, and GUILD. He was never a mechanical god in Paladins and even less so in Valorant, but he has consistently led less skill stacked teams be competetive at tier one EU tournements. Now playing for Yonk.
Saadhak (LAS/BR): IGL, Sentinel, flex: Played secondary frontline(tank) in paladins One of the most accomplished pros in all of Valorant. He won first strike in LA south with the dominant Estral Esports, then led the most accomplished BR team to Masters 1 and 2 titles. Results wise Vikings were by far the most accomplished BR team at international lans as well even if VK looked more competetive. Now playing for LOUD.
frzgod (BR): Duelist, flex, sentinel?: Played Damage/Flank in Paladins The highest earning BR player, he was a staple of the B4 lineup that was one of the few to challenge the dominant Gamelanders. Vikings I have already talked about. He was a star for the minor regions in Paladins. Now playing Sentinel? for Sharks.
payen (NA) Sentinel, IGL? Played Damage/Blaster(AOE damage) in Paladins He was on a few teams like BBG for a bit and has had a lot of success leading TSM Academy to more success than some bigger lineups in NA. I never thought he performed very well at all in Paladins, but he has found more success here. Now playing for TSM Academy.
ninim (OCE) Duelist/Jett Played Damage in Paladins: Kanga were the only OCE team to really compete in the Paladins Pro League. ninim has some big stats in Valorant but mostly against weak opposition with very little in the way of results to show for it. Most recently played for Dire Wolves.
I don't really know where most of the paladins players went other than Faenex who has won some big tournaments in Apex.
