Complete description
They don’t want to over-complicate the description. Any specifications will be scrutinised and penalised to an extent where people will argue the effectiveness of the skills to the second.
They may however decide to introduce this later, where it says for example…
Forceful Greatsword: Gain might (1…5 sec) on critical hit with a greatsword or spear (0 …3 sec cooldown). Greatsword and spear skill recharge 20% faster.
That’s a style they had in GW1 but since this is GW2 and since they have put the concise description as default, who knows.
Also, you have a valid suggestion but your bottom line is unhelpful and pointless for them, since they won’t know what you are talking about. How is it bugged? If it is bugged, have you reported it in the right section.
They are purposely vague with those descriptions to keep gameplay (especially PvP) from turning into a big mathematical equation, and to ease the learning curve.
