I understand that the game mechanics are going far from the original spirit of the d20 system on wish DDO is based.
But "20 seconds" is something totally our of context.
Why the duration of most enhancements (action boost for first) is not based on the "round" and "turn" as spells do?
i.e. the spell haste lasts 1 round /caster level: it means 6 seconds/caster level
buff spells normally last 1 turn (10 rounds) / caster level: it means 1 minute /caster level
Enhancements should follow a duration rule based on rounds and level of the class the enhancement belongs to.
20 seconds is meaningless.
