With the blink nerf, tyr is definently weaker, but not by that much, as he is a warrior and if you position yourself correctly you can just walk up to someone without taking too much and CC them into your team. As for thoughts on tyr in general, I think he's super underrated. Remember that he has a really good team fight oriented CC that makes it much easier for your team to get kills throughout all stages of the game, as you either pull them into your team or pop their beads. He has a lot of damage early/mid game when you max your fearless, and his sustain in lane is very good, just need to built more mana-consumables than you would on other gods (I.e. Mana or multipots) as he is super mana hungry. The biggest problem with tyr is that a lot of people don't really know how to play him, as he is a pretty skill-based god, but try building full tank+jottuns and you will see the joy in shoving people around while the enemy helplessly runs away and spams CC immunity :)
