Thanks for your replies guys. I really appteciate that someone enriches my comments by giving responses.
My focus in my post was not related to that movie star role. I compared him with the main actors of the other maps. It is where my question mark rises.
Thor is not weak and he is effective in offence once he is coupled with Malosi.
It is really difficult to increase the level of troops. It is more difficult than ascending heroes in my opinion. In the case with Malosi, both troops must be at least 11 lvl and they both must mana booster. I believe that as we compare heroes, we should consider them the way they are. Otherwise 30 lvl mana booster troops sweep out the discussion No?
In my opinion SG left a significant margin of buff for his costume (I do not know when he is released) and SG were concerned about OP heroes that have just been released in the 3rd map and decided to shape Thor’s special skill in way that he is good (maybe more of it with Malosi) and average (maybe less of this level) in defence.
Overally I am inclined for a small buff to his 1st charge (blinding percentage could be increased and/or dmg could be increased) to make him more attractive. Otherwise, as long as Malosi and two 11 lvl mana boosters are not around for him, he will not disappear in use particularly after the opening of the 4th map even though he has just been released.
