Like what ship buffs actually bring or remove from the table.
Edit: Btw... the faster you run quests, the less time consuming it gets to buff. So if you run 15 quests with one ship buff session, I don't see how that 2mins couldn't end up, if not winning in term of time in-quest, at least even. Not having to cast any buffs at all or heal through elemental spells for 15 quests is better than 2mins. Now add the loss of dps, etc.
But it trains people to play lousely, that is for sure.
