Shadow Fiend's Skills

Hey, so I started playing Shadow Fiend lately, and he's pretty good, but I've been wondering about his skills lately. It got me thinking about why he's considered a carry. NONE of his abilities scale. Once you max them out, they are permanent and there's no progression.

1) Shadowraze- only does 300 max and mid-late game is not potent
2) Presence of the dark lord- stuck at 6 armor reduction.

I mean, they are still good...but I feel like he doesn't scale as normally as a carry would.

But the thing that bothers me the most is his ulti: Requiem of Souls. Each line does 160 damage and you can send out a max of 18. So let's say I'm in the middle of three enemy heroes and I activate my ulti. That means at most I will only do 160 (maybe 320 max???) to each enemy hero? THAT SUCKS! I read somewhere that you can do massive damage/instant kill if you are literally on top of the enemy hero (done by lothars or phase), but seriously, while your channeling your ulti for one second, there's more possibility of the enemy hero moving than staying at that exact spot. In my opinion, his ulti sucks compared to many other heroes.

He's a midgame carry really, although if he dominates the game and gets well ahead on farm he can be very scary - with equal farm he's not going to beat up harder carries late game though.

Remember that Shadowraze gives you a bunch of farming power, and that does matter in the battle of the carries. This combined with his hard-hitting early game mean he can get off to a really good start, and doesn't really need any farming items. (e.g. Heroes like Alchemist and Doom Bringer don't get great stats gain or scaling passives either (ok alchy's ult is pretty good) - a lot of their carry potential comes from their awesome farming ability - you possibly even say the same for Anti-Mage)

Requiem - distance from target is the vital factor - at point blank range enemies can be hit with multiple lines for big big damage. Keeping the enemies stationary relies to a point on allied abilities - if you try it when the enemy is trapped by Black Hole or a host of other AOE stuns/slows then you can utilise it's full potential.

At first Shadow Fiend could seem a mid-game carry like Queen of Pain or Templar Assassin: high damage nukes that do their best when ganking and give easy kills with a Blink Dagger/ Blink (even though some people prefer Shadow Blade on him). But, if you look closely, his Necromastery does a very good job at giving autoattack power: just like Drow Ranger's Marksmanship, the attack damage increase could be treated as an item that makes your "carrying" much easier so that you can focus more on getting kills than gold, thus avoiding the safe lane. Plus, his agility gain is not bad at all. He's best used to carry the mid game, but works well in late game too.

I'd say, Shadow Fiend can carry a game by himself though he's not as reliable as a Phantom Lancer or Lifestealer. The reason behind this is that the majority of his skills focus on getting kills exclusively: Necromastery for autoattack power, Presence of the Dark Lord for armor reduction and Requiem of Souls for initiating.
