Cool, I'll PM you. I can't sneer at Gold as I'm an even dirtier Silver.
I AM NOT AN ANIMAL I'M A HUMAN BEING!
Some thoughts:
-I think you bought too much regen, some stats would have been good, like 1x tango 1x salve 2x branch + clarities
-Very early game: You were too close to the creeps when you harassed them, pulled aggro and got attacked yourself by the creeps. The way you do it you nearly harass yourself more than them.
I would recommend you to position yourself slightly differently, maybe toward the right side of the lane under the first trees. It would be more offensive but probably safer as if you can get into such a position that you don't pull aggro while harassing.
And don't right click the hero until you are sure you're in range, because otherwise you're gonna pull creep aggro even though you don't get the attack off. Instead move closer to them first then attack.
Also, harassing to much while drawing creep aggro makes it really hard for the carry to farm.
-"Wooden PC", classic dota terminology. I approve.
-You probably shouldn't skill liquid fire (e) so early, instead get ice path (w) at lvl 1 (as you did), and then max dual breath (q) and after that ice path. In some cases you want to get ulti at 6, sometimes not, same goes for liquid fire if you can push the tower or get great auto-attack harass off.
Mana isn't really a big problem for thd/jakiro as his int is very good.
-I think you generally position yourself too close to the creeps, that's what caused the first blood on you imo. Try to keep some distance, sometimes on your side and sometimes on their side or on the side (secret shop/woods).
-When you buy sentries for the lane I wouldn't recommend placing them right away, instead wait until you know he's on the lane and you know that you can get the kill off/some good harass. They only last 3 minutes after all. And even though you put them up, you didn't take the chance to ice path bounty hunter when he ran into them. Could have stunned him and nearly drained all of his mana together with AM.
-When you're defending a tower, you positioned yourself in the front of it before your creeps came, very dangerous. I think you should take a more defensive position, as it gives you more time to set up your skills and you have a quicker path to safety.
-Generally for early game, I would recommend you to spend more time on denying creeps and focus the harass on the opportunities that are actually really good, rather than trying to harass all the time.
-Sadly you lacked a lot of impact because of your skill build, dual breath is an amazing skill that does a lot of damage in an aoe and slows a lot. On the lane you probably want to get the enemies away from the creep wave and then use it and force them to run away even further. On top of that it's an amazing anti-pushing tool, however it was nearly a bit too late when you got it, and that's not surprising, it's very hard to get levels as a support when you're behind and constantly have to help in fights where you are at a disadvantage.
-General tip: you probably want to carry a tp pretty much all the time, saw a couple of times you were home and had the gold to buy one, but didn't! Any hero, even carries should carry a tp at all times, that's my opinion at least.
-Warding is another thing, I think that's something the safe lane support should generally be responsible for, however I'm not sure if you should focus on that right now. Get the lane play down first, and then implement the warding rotation after that. Or even better, buy wards that the mid can place, then you don't have to move from the lane.
-As you can see, there's a general theme of positioning. Dota is very much about positioning, maybe even more than the other arts/mobas as the turn rates and shit like that are a lot longer. It doesn't help that you played thd, who has a notoriously slow turn rate and cast times (but no doubt, it's definitely a very good hero, and I'd definitely recommend you to keep playing him).
-A thing that I liked a lot is that I think the ice paths got better the later the game got, so even though it might look like a lot of "criticism", I think you're definitely doing well.
I hope it's of some help at least, I'd recommend you to watch the replay once again and really think about how positioning (with dual breath in your skill build) could have been better. I can't comment too much about the late game though, it was pretty much a stomp, so it didn't really give me any impression of your ability of playing late game.
What are you considering the cutoff DBR for "Scrub League"?
It's definitely 2100.
