cant help you people, they bought no, or next to no damage, and old sunfire was a pittance compared to what any other ADC or mage has the potential to put out. see jinx rockets, crit all 5x members for 900+ damage.
old sunfire was perfectly balanced and great even as a rush item. im sorry you dont like dieing to tanks, but guess what, its not the tank that beats you, its your improper itemization that gets you killed. he builds sunfire? how about you build some magic damage? or even a cleaver if you're a die hard must build AD person, then you can still win. or how about he has sunfire, so hes pushing by default because he cant turn it off, and as a result he exposes himself, and you get a gank on him?
maybe, just maybe, you should stop trying to 1v1 all in him and accept he reached a powerspike and you need to approach a different method of killing him.
no?
too difficult for you?
the item was not oppressive, you just didn't know how to handle it.
