Started playing at the end of Season 4, this is the biggest difference to me now

There is almost no room to make any mistakes in laning phase, especially as an ADC or immobile champ that has no self-peel.

There were times I'd play ADC recently and just eating 2 spells from a Brand or Bard combine Arcane coment and Electrocute respectively would cost me nearly half my HP bar at LVL2.

Being immobile is such a liability now, especially with the existence of Sudden impact and prevalence of Conqueror, there isn't much you can do when a champion that is mobile and runs either of these gets the drop on you or simply just goes for it.

Ignite does way too much damage.

This shouldn't even be in the game.
