Alright let me say this as objectively as I possibly can.
First things first, Syath is an excellent high-Open pocket. Is he the best? Maybe not quite - but he may well be at the end of next season. I don't think I can think of anyone who's progressed as quickly as he has in skill over just one season.
Truth is, he's one of the most dedicated pocket players you could get - he has a winning mindset. If you're just looking for a pocket for your mid-high Open team that just wants to play the season to see where it goes and maybe do your best but without any major ambitions, you've got the wrong guy. If you have a high-Open team that can do well in the season but has an ambition to be able to compete with the best and move up the ranks, this is who you want. He's only human, and he can get distressed, but it'll always be because he wants the team to do the best it can and improve wherever possible. I give him a few seasons and he'll be a big deal in IM.
Also, his shotgun DM is really, really good. Like damn. Please.
EDIT: His sense of humor isn't as good as his shotgun DM
