Has there ever been a good meta where Morphling was viable? Including DotA as well.
I take it you've never heard the phrase, to get "Morphling'd" lol? Morph was a god during TI2 and he received some of the biggest nerfs any hero has ever received in dota up until then (in one single patch). So the hope for every OP hero afterwards was that they wouldn't be "Morphling'd," but receive some surgical treatment lol.
I don't see why you'd want to pick morphling except for a super pocket draft, as a carry he's just.. not convincing ?
He is really really really good in 6.86.
The adaptive strike damage buff is huge for early levels and the manacost reduction is huge for later levels. Ethereal blade has been buffed the last few patches, linkens has been buffed tremendously in the last few patches, and the biggest buff of all was to his Morph shift rate. It shifts at faster intervals and it straight up shifts faster at level 3/4 I believe, double the speed of last patch at level 4. So as long as they don't have a silence, you can pretty much just run around at 500-1000 hp early on and never die, because you can always shift health instantly, on demand.
Late game when you have plenty of str/agi to work with and you're not worried at all about silences because of you'll have some combination of linken's, manta, or BKB; you pretty much feel like a god--how the fk is anyone going to kill you.
