i start flask, ward and pot on most tops, boots on mids without self-sustain, dorans ring on those with self-sustain, longsword and pots on adc without healer, dorans blade with healer, and fairy charm 2 greens 1 pink and two pots on supports
Pots and wards are unnecessary on most supports, you shouldn't need more than three wards (unless you are playing a very specific strategy based around that) and tons of pots arent really that great - you shouldn't be getting poked horribly as support and if you are then all the pots in the world wont help
