Pangolier + Weaver

Why this works

Trying to lock down a key target in a teamfight reveals the core problem here. Pangolier's Rolling Thunder is a chaotic initiation, scattering enemies rather than holding them in place for follow-up. This directly conflicts with what Weaver needs to be effective, which is a focused target to unload damage onto with Geminate Attack. Since Weaver brings no lockdown of his own, he's often left chasing opponents that Pango has just knocked out of position. On top of that, both heroes deal primarily physical damage, allowing enemies to get huge value from single armor or disarm items that work against both cores.

This dynamic leads to messy, uncoordinated mid-game fights. The lineup lacks a stable frontline and reliable control, putting immense pressure on the other three heroes to provide both. An enemy team can often ignore the two slippery cores, run straight at the supports, and collapse the fight from the inside. Once their teammates are gone, Pangolier and Weaver rarely have the collective power to win a straight-up fight, forcing them to disengage and give up map control. The game becomes a scramble where neither hero can properly enable the other's strengths.
