how to play during the assasin meta as a support?

All ive been seeing in bot lane on the enemy team is assasins/high damage casters, and a ton of pyke. How can I play against that? I had been maining enchanters but between the nerfs to early cdr, shield/heal power, shields, and mana I can barely compete with one high damage enemy much less two.

In the old days enchanters were viable because damage wasnt so bursty that their single target heals/shields could contribute a lot to a team over the course of fights due to longer durations. Then enchanters were viable because they were good at keeping 1 target alive which synergized well with adc's who could do significant damage if kept alive long enough. Now, enchanters can barely keep 1 target from being instabursted assuming none of their skills are on cool down and even then the target has a huge chance of dying a couple seconds later because assasins can flash+right click to do like 20% of a targets hp in damage or more as soon as the enchanters skills are down/on cooldown.

Looking at other support classes we have the tanks, the cc, and the dps left. Tanks arent actually all that tanky in early game and will easily run out of mana with the frequency that some meta picks can poke, CC heavy supports while good in theory are generally a bad idea simply because they tend to have higher cooldowns and without the ability to stop both the enemies in bot lane, (with the exception of maybe like lux) they will eventually lose the lane from being outtraded. Which really only leaves damage heavy supports as a viable option in this meta. Which is very sad because now literally every role is ruled by high damage champs.

If anyone could offer any tips thatd be great.

TLDR: riot somehow managed to make a meta worse than the adc meta.
