Patch 7.22f is similar to the previous minor updates. In fact, it only features some tweaks to a few heroes and only one item. After all, it's very likely 7.22f will be the last patch before The International 2019, so let’s take a closer look at the changes. Hero WinnersTinkerTinker is the biggest winner of 7.22f, hands down. The good-old mid hero received three buffs to his talents, which will definitely boost his potential. Valve has increased his level 10 Talent’s cast range, as well Spell Amplification. In addition to that, the level 15 talent Life Steam has been changed to +11% Manacost/Manaloss Reduction, which is just insane, especially during the late game.

These changes allow Tinker to have a lot more sustain than before. InvokerValve also broke out the buffs for Invoker. Apart from his base Intelligence increase, his Cold Snap damage has also been buffed by a significant amount, which is very welcomed for all the Quas/Wex Invokers out there.

Despite the changes, it will still be hard for this hero to become a top pick. In all reality, there are more heroes that do Invoker's job better than he can. Number three on this list is Drow Ranger. The annoying carry received an increase to her strength and agility. In addition to that, her level 15 talent is now even more powerful - +40% Gust Blind.

Drow has always been and on and off hero in terms of professional games. These changes will probably boost her popularity in draft at least a little bit. Dragon KnightDragon Knight is next up. Firstly, Dragon Knight's Elder Dragon Form Scepter now has 40% magic resistance up from 30%. In addition to that, his level 20 Talent/s GPM is now +210 instead of +180.Apart from the ones mentioned above, buffs were given to several other heroes as well: Chaos Knight, Clockwerk, Keeper of the Light, Lycan and Underlord.

The second hero in this section is Ancient Apparition. Ice Blast now requires more mana and his level 15 talent provides 5 less HP regen. Despite the fact that those changes seem minor, Ancient Apparition is very susceptible to hero changes. We don't know if these nerfs will make him less popular than he already is, but only time will tell. Outworld DevourerThe last hero on this spotlight list is Outworld Devourer. There were tons of changes done to the legendary mid laner in the past which changed him dramatically.

In patch 7.22f, his Astral imprisonment cooldown was increased by 2 seconds on each level. In addition to that, Sanity's Eclipse mana cost was also increased by 125 at level 3, which is a lot. Despite that, I personally believe that Outworld Devourer will still remain one of the top mid laners right now. His damage output and farming mechanics are just too good to pass up.
