Mekansm

Man, at 1775 gold, it is the cheapest team-wide impact item in the game. One press heals every ally within a 1200 radius for 250 HP simultaneously—not one ally, not a targeted unit, everyone. In a mid-game fight where five heroes are sitting at 60% health after the first exchange, that is a net swing of potentially 1250 HP distributed across your team in a single button press. No other item at this price comes close to that fight-turning potential.

The passive aura is doing quiet work on top of that — +2.5 HP regen and +3 armor to every ally nearby, all the time, just for having it in your inventory. In the 15-to-25-minute window when heroes are grouped and fighting constantly, that sustained regen and armor add up across every single engagement.

And right now in the current meta, Dotabuff's own analysis is saying Mekansm into Guardian Greaves is universally powerful. That is not an accident—healing supports are strong, the item is cheap, and the mid-game burst heal is as relevant as it has ever been.

The first major item on positions 4 and 5 supports those who are playing in grouped, fight-heavy lineups—Chen, Undying, Dazzle, Omniknight, Io, Warlock, and any support whose team wants to run at people before 20 minutes. The timing is 15 to 20 minutes. You complete it, you group, you fight.

The draft signal is simple: if your team is playing 5-man Dota and skirmishing early, Mekansm multiplies every fight. If your team is split-pushing and farming lanes separately, the 1200 radius heal is wasted half the time.
