thinking about this combination (R1 & L1) would give more then 5 combinations it would actually give 7... yes i said 7, lol you have these combinations: Tier 1 - Quick Release (tap button) for both R1 & L1 this makes 2 abilities. Tier 1.5 - Charge System (hold then release of the same button) for both R1 & L1 like crooking a grenade / building up space magic. Tier 2 - Charge & Execute (Hold then execute with alternate button) Charge with R1 and then tap L1 to execute, and vice versa (charge L1 and execute R1). Tier 3 - what i consider "Ultimate Ability" Charge both and either Hold or Release depending on the "Type of ability". a good example of a Tier 3 ability would be like a area dome shield, would be a "Hold" when an explosion type would be a "Release". of course "Hold" would render the player unless but for area dome shields can protect anyone inside of the dome and can buy the player time for other cool downs.
