Weaver's Return To The Meta
Weaver has emerged in recent patches as being one of the strongest heroes of the meta. His Aghanim’s Scepter upgrade had brought some attention to a Support or Offlane Weaver, but he’s received a series of buffs that has brought him back as a potent carry. Weaver was the 3rd most contested hero overall at DAC Qualifiers and the 2nd most contested carry, narrowly behind Ember Spirit.
Valve has minorly nerfed Weaver in 7.01 and 7.02, but prior to that, since the introduction of his Aghanim’s Scepter upgrade in 6.84, he has been getting buffs patch after patch. From 6.84 to patch 7.00, his base damage was increased from 50-60 to 55-65 (now back to 53-63), Agility Gain from 2.5 to 2.8 , Shukuchi now phases instantly, and The Swarm gained buffs in mana cost and damage that created nightmares for opposing offlaners.
Weaver’s New Talents
The difference in win rates of Weaver’s Talents
Weaver’s bugs from The Swarm were a little ridiculous, before Valve nerfed its damage in 7.02, so that the damage output that players used to have at level 1 is now scaled to level 4 of the skill (from 20 to 14/16/18/20). The bugs do a bit less damage, but why they’re really strong is they allowed Weaver players to dive opposing offlaners right under the tower, especially in the early game. It was and still is a well spent value point for any Weaver in the early game, but especially for support Weavers it felt too strong. One tip: Poor Man’s Shield stops the bugs from damaging you, though you’ll still receive armor debuffs until you get rid of them.
Patch 7.00 introduced a group of talents that opened up a more aggressive playstyle for Weaver players. Early extra Shukuchi damage and more HP at either lvl 10 or 15, along with 
Dragon Lance’s +10 Str component, shifted Weaver into an early to mid game contributor in team fights. Moreover, the bonus talent stats made him less item dependent, making him just as versatile for less farm-oriented roles like as an offlaner or support. That flexibility in lanes is what has made him a valuable pick in the meta.
In patch 7.02, Weaver received a boost for his level 25 talent, increasing the Magic Resistance bonus from 20% to 25%. This hasn’t deterred players from picking what is by far the superior option: +200 Shukuchi Movement Speed. Skill altering talents like this offers an upgrade that no item can replace. The net win difference here is +5.5% for players who opt for the bonus speed, which consequently also boosts his distance travel, similar to Puck’s Illusory Orb upgrade, which is also favored by 5.9% in win rate.
More Flexible Itembuild

One thing that pub players consistently do wrong is building 
Linken's Sphere for every game. From our pub stats, people more frequently end up with more Linken’s Spheres in the inventory than Power Treads, Town Portal Scrolls, and Dragon Lances (to be fair, TP scrolls are low priority items across all heroes in pubs).
Linken’s may be a core item on Weaver, but it has become much more situational than ever before. Now that Dragon Lance is a valuable early item, pro players especially have opted for more flexible and stats oriented builds. A buildup of Treads, Aquila, 
Blight Stone, and Dragon Lance is sufficient for Weaver to contribute in the early phases of the game. This more aggressive playstyle also complements Weaver’s new, early talents—whether it’s added Shukuchi damage or more stats, it enables Weaver to enter the fray. The current meta encourages scrappy engagements early on and these items ensure that Weaver can have as much impact necessary to fight with the team.
These items also allow Weaver to transition seamlessly into a more carry oriented build. When later building into DPS items such as Desolator, Mjollnir or Daedalus, the added range and stats from Dragon Lance make Weaver more well-rounded and harder to kill. Some pro players have even opted to skip a defensive item like Linkens' or BKB entirely, like TnC's Raven in the recent Starladder LAN.
In The Current Meta
With the nerfs over 7.01 and 7.02, Weaver is seeing a decrease in play, especially in the ongoing Starladder i-league tournament, where he’s holding a 57% win rate across 7 games, including a dominating game by VGJ.Agressive against wings.gaming.
Weaver has ascended into the meta through the confluence of several factors: the versatility to be a support and an offlaner, allowing captains to build flexible drafts; a sequential of minor buffs dating back to 6.84; and the arrival of 7.00 talents and Dragon Lance that opens up an early, fighting build that can transition into a late game, hard-carry role. The minor nerfs may have been enough to knock Weaver down a little in favorability for pros, but Weaver still remains a top pick for pub players, who are still catching up on pro trends.
А что это у нас тут? Это же сапожок на вивера, ахахаха наконец-то. Да-да-да, очень хорошо, очень хорошая сборка, а главное гибкая. И совершенно похуй, что ты выкидываешь почти полтора кэса в помойку, ведь как можно не покупать сапог? На всех героев покупают сапог и на этого тоже купи. Купи костыль на вивера, ну мам, ну купи!
I'm weaver spammer- i can addthat if you want to catch enemies, try new sange and yasha + maelstrom - it is impossible to escape from gemine attacks ;]
can someone please elaborate weaver in support perspective?
i hope he doesnt get nerfed to trash in 7.03.
nice hero for mmr boosting
