Heroes such as Slark, Sven, Tiny, and Pangolier enjoyed the mana regeneration, the stats, and the active as well. The nerfs to Echo Sabre are justified mainly because it was too efficient. Expect playmaking mids and non-flash farming cores to make a comeback. This nerf to stacking means that the meta heroes (Sven, Gyro, Luna, etc) that loved to clear stacks will now have to wait a bit longer to come online. Securing ancient stacks meant securing the game. In the previous patches, the early and mid game was focused on stacking jungle camps for your team, and conversely, raiding the enemy’s stacks.
This is the biggest meta-shifting change in this sub-patch. A stacked neutral camp – achieved by pulling creeps out of spawn boxes as timers hit minute mark (via Medium/Mike)
