Is Tinker trash now? He wasn't good in 7.26, and the newest patch seems to have nerfed some of his most popular items: Kaya/Bloodstone no longer reduces mana loss and Dagon gives less Int.

Tinker is a hero that teleports in, spam all his spells, then gets out. Both of the above changes will reduce how many spells he can use in one go. He doesn't care too much about the extra magic resistance or spell lifesteal as he is dead if caught, and the extra Str and Agi from the new Dagon will be minimally beneficial compared to the previous Int.
