How can you say it doesn't change his damage much except for where it significantly changes his damage?
Besides the fact that executes are gimmicky and lame, Sobek can now deal significant damage to both carries and tanks without building any damage. How is that good character design? Why does sobek need to have so much kill potenial? He already has 3 forms of cc, a passive that increases protections, CC immunity, decent-ish escape, and (now) 2 abilities that heal. Why does he need to have an AOE execute? It makes no f**king sense. He is going to be a nightmare to balance.
Yes, he can only now do significant damage to carries, compared to S1 where he'd only do a pitiful 900 base plus 80% int to them.
He's just been given a tankbuster ability that will be useful once every so often, literally nothing game breaking if you look at it for more than 2 secs.
