I think the tooltips from abilities, items, champion points, etc, should be upgraded. It's not really hard to do, i suppose one day of work. It's just text editing after all.
Many perks from the champion points trees are difficult to understand. Like befoul, which should be "increase the healing reduction from the Defile debuff by %". And there's much room to understand the over time effects and direct damage effects.
And item sets that don't really respect the description. Take Selene for example, it says it procs from direct melee damage, and now take jabs, which theoretically as everyone told me, direct damage that will proc the set is only the first hit, the rest 3 are not, but Selene can proc from any of the 4 hits. So from here i understand that all my 4 jabs ticks are direct damage. But this ability's damage is increased from the Thaumaturge champion perk.
Abilities also don't state how are increased more, from stamina or weapon damage. A player should not go on a wiki to learn mechanics, the information should be present in the game. The F1 (help section) don't offer such informations, like what abilities are considered over time and which ones direct damage. There's some aoe abilities that deal direct damage (like blade cloak). This section tells things like "click on the + icon to invest the point" well fine but give some advanced important information.
There's too many examples to cover them all here, but in the end my suggestion is to update the game tooltips and information.
