Early to mid game I just shove the wave to get priority, to make it easy to punish roams from enemy mid laners as well as getting priority for my jungler.
Additionally, I like to provoke enemy junglers to gank me, especially once I get level 6, as a 1v2 scenario can easily be turned into a double kill with R
Generally I like to play for Towers, generating pressure and drawing attention by simply splitpushing.

I generally go for Q Max, because it's better for pushing than E max
In laning phase I just lookt to hit E and smack their soul as usual.

No matter how many times I die, I will try again and again to push those minion waves.
"Die for the tower" ~me, sometime in 2022

As Support I like to rush into a brush near enemy tower and look for an E on the ADC to get some easy gold and damage, as well as annoying them with tentacle spawn.
Early on you can use Q to help push, but once you one shot back line you have to be more careful as to not take too much CS.
General gameplan is to just keep damaging them through your E.
