Congrats on Grandmaster. Dont ever let any player higher or lower in elo take that achievement from you. You're insane man. Keep up the skills on briar!
I love invading with briar but I always waste a lot of time returning to my jungle if you didn't countergank the enemy jungler mid what would you have done? another thing, is there a video of yours where you explain solo invade with briar? I know it's not an exact science but I'm sure there will be some trick to invade without committing suicide and wasting farms and time XD
If not counter gank I would've done my red to my bot side. Their wolves and your krugs are too out of the way. Here is the original video about this pathing: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3JDrMH899qg.htmlsi=5sm0v5-8MyAAHb2i Saving your Q for the right target is the key to not suiciding
