Tips for dealing with premades as a solo player (Especially as an ADC or Toplaner)
Feel free to add to this if you'd like , this is for everybody.
When playing ADCs, I've constantly been the victim of 3 or 4 man ganks. The best tip for this is learn to freeze the lane to the best of your ability and do your best to be on the same page as your support. Now more than ever, people really need to learn the importance of warding especially if you want to climb. This goes for top lane too. Your role is literally to carry, so everyone on the field is going to want you dead.
When playing top lane, make sure you also freeze the lane when playing squishier characters like GP or Yasuo. If you're against a top and jungle pre-made, you need to ward and not push. Wear the enemy jungler's patience thin so he/she goes to other lanes. If you're trying to freeze the lane, you shouldn't have too many issues maintaining your farm.
