Thing is, wards are so efficient to snowball an early lead (drake, turrets, successful ganks) because the provided gold on everyone besides the support will let them powerspike quicker than the enemy counterparts. Oracles and pinks are so vital in pulling off good ambushes/fights and deny the enemy all their vision, making cs'ing impossible.

The champs you mentioned can be played as "supports" as in "being botlane and warding", but they wont provided the cc that youre talking about. Shen will die if he dashes in, dongers grenade is dodgeable by rhesus monkeys, same goes for Anivia and Gankplank is an allaround trash champ. Tell me something support GP offers and Sona doesn't?

Overall its just a weird opinion in this wiki that you have to play against the meta for whatever reason, nearly every blog besides fistful of forces ones are advising to break it by unleashing stuff like Toplane Leona, Mid Nami and adc Malz because its so funny and cool. You guys act like its bad or something to play the meta.
