I have suggestions for using easy 16 Skills with a Gamepad. The Inquisitor Class is Changed to 1 only but can have 2 Weapons Sets and Ranged Two Handed Weapons are Combi Weapons using 2 different Weapons but only the primary Weapon can use normal shots, the secondary weapon only uses the Cooldown Weapon Skills. The Inquisitor Class has 1 Psionic Set with 4 Different Skills and 1 Summon Set which summons Minions for a short Duration of Time but with Long Cooldown. You can switch the 4 Skill Sets with the Gamepad Arrows.
The Weapon Balancing should be more like in the Tabletop. Meaning a Melter has a long Cooldown for normal Shots but can Instant Kill a Space Marine or does very Heavy Damage against stuff like Dreadnoughts.
