Can agree with that. Everyone in this game has the attitude that 1v1s is everything. That's because usually there is some ego contest between two people and they think whoever wins is who is right. This is not true and not every mastery build is equal. Some are better 1v1, 2v2, zergs, farming etc. Obviously you will always be able to damage someone, but the extent of which is different.
That being said, that doesn't mean certain balances shouldn't be made. Like take Fan/pipe/poison scalpel for example, that should definitely get fixed.
I think Lightning does what it is supposed to do. Fire on the other hand is full of bugs that never have been fixed. The firewall stopping chakra charging, people not landing in fire bullet animation, simple stuff like that, that screws you over in a fight. Vortex itself is extremely underwhelming and could use a tweak.
