(Referring to his raven familiar he gets when he uses portal.)
Anyone wish medivh’s crow acts similar to rexxar’s bird? I really think this kind of engage literally is pointless when half the time opponents be thinking. “I’m going to pull this dude from his portal and kill him.” Meanwhile the crow does absolutely no benefit whatsoever? Plz make the crow act like a boomerang like rexxar or make it hit people through the portal.
They are addressing the Raven Familiar lvl 4 talent of the hero.
“A Raven Familiar joins allies each time they use a Portal. The Raven will dive at the ally’s next Basic Attack against a Hero within 5 seconds, dealing 114 (+4% per level) damage and Slowing them by 30% for 2.5 seconds.”
Its mostly just a damage boost. I think the idea is to have your team emerge from a surprise portal and nuke someone.
The only way that raven would work is if there is a basic attack that has a very very farther range that it be less possible for opponents to pull you and put you into a dangerous position. 
i wish that familiar just flew into the portal and bird made the portal turn into flames or something with a random effect. Like pushing away anything that’s near the portal with one few damage.
Medivh doesn’t need more range because he has portals that should bring him out of any dangerous position. The raven familiar is nice because everyone who uses the portal gets a buff on his next auto-attack. If your whole team uses the portal and everyone does one auto-attack then you can get a lot of value from that talent.
You basically said that Medivh’s best talent is pointless? 
It can be harder to notice the benefit compared to his other two level 4 talents if you aren’t actively looking for it.
Congrats on the 10k 
And it’s a RAVEN not a CROW learn the difference OP
Just one of the things in this game differentiating ultra high MMR’s from highs, mediums and lows.
Hint: Properly executed Raven Familiar portal ganks can almost instantly kill a player who is slightly out of position.
But you’ll probably never see 5 player portal ganks outside very high SL or CCL games.
It’s the best talent on his lvl 4 by a long margin.
It also adds a really useful soft-cc (slow) on the target after AA.
Yea, Raven Familiar deals 114 dmg (lvl 0? 1?). You can multiple it by 5, so 570. And You can do this at least twice, so 1140 dmg. Just from a single lvl 4 talent.
And it also slows… :'D
If you are chasing someone, and place the portal, 1 raven slows the target, the rest can catch up. But their ravens can also apply damage. 5 ravens of 100 damage at level 1 values of HP adds up to a lot of damage (note that a lot of heroes are below 2000hp at level 1).
Its an extremely strong chasing tool, and its very likely ment that you arent supposed to deal damage with all 5, but its very well doable.
It also is good for chasing since you can portal ahead of the victim and then hit them with the crow for bonus damage and slow which allows more hits to land on them.
L2P issue.
Please L2P
I think it’s broken the Familiars can trigger damage and slows an unlimited amount of times, thankfully almost no player can play Medivh properly or that would become a problem.
I’ve been faced with that situation one or two times, and it wasn’t fun (except for Medivh’s team).
Though it also depends on having good teammates who actually use the portals, making it more ideal for a voice comms match.
If your opponents are thinking that, then you’re doing it wrong. When you do it right, your opponents are thinking “$#!^, I need to get away!”.
lots of good analysis in this thread.
If you’re using Portal to chase and kill, that would be the talent to pick. Don’t sleep on the slow effect.
i benefitted greatly from this thread thank you op
was picking armor before
the raven portal thingamajiggy is quite possibly the best talent in the game 
this idea is for a small damage extra when coming out of portal . specially useful when chasing fleeing targets. the slow is a nice complementary to it and allows you to walk a bit and usually land an extra arcane rift.
