how could we rework sunfire?

I've wanted to see more "burst tankiness" items myself. Things that help a tank charge into the middle of a team fight without making them impossible to kill if you have a few seconds to kite them.

For Sunfire I thought you could make it blind people who haven't been hit by the immolation recently for a short time. Like a 1 second blind on anyone who hasn't been immolated in the past 20 seconds.

It's still a decent bruiser item: it gives 45 armor, 150 more flat hp than cinderhulk, and its passive is static (the base damage is 1 damage more than cinderhulk full, with 66% of the level scaling, so it's not terrible for short trades and skirmishes).

Maybe instead of changing sunfire's cape, we could introduce a new health (maybe armor) item for top laners.
