The idea is pretty simple after a run or two.

This tactic is mainly concentrated to Arena, but all the modes translate to it eventually.

You want to rush in numbers grouped closely together and pick off 1 target.
Do not attempt attempt to push, but don't fall so conservative that you don't rack up kills.
If you see isolations or single-target ganks take them.

+5 Man Group Rush; able to rush against early conservative-play aiming one target to compensate
(Vulnerable to early pushes if nothing is baited)

+Strong Early Mid-Game if you're able to expose the tank and not fall into push-baits.

-Unable to Boom late game defensively, transition to expensive builds doesn't translate as good if forced to stay offensive.

Sell Polynomicon for needed CDR Item,
once you've bought Potion of Magical/Physical Might after 6 items.

Heavenly Wings Upgraded helps solidify midgame snowballing for 5 man rushing with auto-attack emphasis.

Meditation works great for extended pushing but can be opted for anything else.

Side Note: If the tank is the peeler you can replace Obsidian Shard for Magi Cloak to gang rush the backline support and the tank will eventually lose lane integrity.
