I stole baron and won the game because of a blasting cone

I couldn't get the replay(rip replay.gg didn't record that game), but as you can see, we had a huge comeback at ~28 minute where we aced the enemy team and took down 2 towers, but then my team overstayed with low hp and top mid adc got caught and died. Our support also died not long ago, so I was the only one standing while the enemy went for baron. As talon I had my stealth and parkour so I was thinking maybe I could make a hero play. The enemy thresh did a great job by standing at the entry of the pit and putteddown the box and turned on the oracle. I saw the Baron still had 5k HP and if I run into the pit right now I will get immediately deleted. So in stealth I ran up and looped around to the back of baron pit. I waited a bit and parkoured through the wall in attempt to get the baron, but the enemy Lee sin, again, did a great job by kicking me back out of the pit(obviously my ult stealth has been gone). I thought it was over, until I realized there was a blasting cone plant at the back of the baron pit. With a last hope attempt I proced the plant and it knocked me back in the pit to get the smite on baron.

This seems like a cool play of course, but it really isn't fair for the enemy team. The plant spawn is random, and they can't destroy it before it spawn. If they waited for the plant to spawn my team would have respawned and the following teamfight will not be good for them since they got low from killing baron. Thresh zoned me very well and Lee kicked me to deny my parkour steal. Losing a baron due to a gimmick RNG plant really doesn't feel fair.
