HyperLeague Heroes v3.0 is live now and there are tons of new features and enhancements. The updates will be detailed across several posts. The first feature I'll cover is perks and formations.
Each character now has 3 unique perks, the one that activates depends on where that unit is in the formation.

Example: Singe boosts the crit rate of nearby heroes from the frontlines, gets increased speed from the center, and all adjacent heroes get +50% more exp when Singe is in the back. Remember that you can only have one these perks active at once so you'd have to place Singe where you need him most.
Units can be rearranged on the fly and as much as needed so you can adjust your tactics to the current situation.

Here are some more example perks:
-Vito / back - adjacent units take 30% less ballistic damage
-Nurse / center - allies recover 2x more HP when healed
-Ice Age / front - freeze all enemies for 15 seconds when landing a crit
-Gunslinger / center - standard attacks do 1/2 damage but hit all enemies
You can also right-click to see fighter details such as the unit's perks and which perks they're being affected by.

Units now also have two types - ranged and close quarters. Close quarters units do full damage from the front, 75% from the center, and 50% from the back. Ranged units do 100% damage regardless of where they are in the formation.
At the same time -
Your teammates are targeted according to how close they are to the frontlines. Units in the front are very likely to be targeted, units in the back are unlikely, so it's important to take your unit's bulk into account when choosing your formation while also considering the damage they'll do given whether or not they're ranged or close quarters.
That about covers it for perks and formations, next time I'll cover character tiers.
