The meta in Dota has developed a lot in the last years and arguably one of the biggest changes is the introduction of more items and heroes with defensive (save) mechanics.

With such mechanics being widely available, it becomes very difficult to initiate directly on an enemy frontline core, simply because the enemy team is likely to save him and counter-initiate if they are in range.

This has made it pretty commonplace to have two kinds of initiators in the game. One traditional team fight initiator/counter initiator, usually on pos. 3 (in this case Void), and one mobile hero who can jump on the backlines.

A hero who focuses the backlines is not a new concept by any means, but drafting both of the roles mentioned above are becoming more and more commonplace.

In the past, Void + Storm would have been considered a bad combo simply because they have difficulty focusing the same target (Storm deals damage in short-range, which makes it difficult for him to contribute during Chrono and difficult for Void to follow-up a Storm initiation).

In the current meta, however, Storm + Void don’t clash as much because they have different jobs in fights and their roles actually complement each other. Void wants to catch the enemy cores, while Storm wants to jump on the backline supports with saving mechanics (in this example Shadow Demon and possibly Abaddon) to prevent them from saving their teammates.
