If contacting units on 117-121 was that easy... the game would be primitive... And who prevents you from taking Thorgrim, for example? There are many counter-strategies... And regarding Solmyr... He has many drawbacks. By week 3-4, he will most likely become useless... Do you have any objections?
Is this some kind of joke? Where does it say you'll even make it to week 3-4? ;)
There are certainly strategies: Thorgrim, tactics + mass haste, cloak or amulet, antichain. But I still doubt that Solmyr won't be overpowered in the long run. And Dymir with Jeddite + Tant are heroes of the same caliber... Tant is 100% overpowered.
