This is the most common reasoning among players, but it’s incorrect.
I was Lvl 2 when I started soaking. Now, most players should know that chasing kills early game is stupid, because an enemy kill is worth less than a minion wave. But this works both ways.
At lvl 2, a minion wave will be worth 492 xp, with 82 xp per minion. (Xp scales with time, not levels, but between lvl 1 and 4, the value per hero level will usually match) Now, if one of your team mates dies, they will give about 348 xp to the enemy team, not counting underdog bonus. Which puts you at a net loss.
So if you leave your lane to go look after a team mate, you are giving up 492xp, to potentially prevent a 348xp gain for the enemy. And I say potentially because your team mate may very well survive if you don’t go to them, or they might die anyway if you try to save them. But your soak is guaranteed. So in essence, you are giving up on a $500 check that will be handed to you, in order to have a chance at $350 in a slot machine.
Your team mate’s life at lvl 1-5 is worth less than the minion wave you will miss.
In that replay, I soaked about 1488xp (two 492xp waves and one 504 wave). But I’m being told to give that up to prevent my enemy from potentiall gaining 350xp from an ally kill.
Your instincts tell you to try and save your team mate, but the numbers dictate that you let them potentially die. Because leaving the lane to try and save them is a misplay that will cost your team. It doesn’t matter if your team mate die while you soak a lane at lvl 2.
I’ve seen diamond and even master players who don’t understand this. And then wonder why the enemy has an xp lead.
So unless someone finds me a good reason to give up 1488xp in favor of 348 ( or even 504 in some cases) I will keep making that call.
In essense I am asking you to prove that statement.
