You do realise you are comparing with only you having to debuff for your own,right ?Strawman is a good indicator,parsing stuff at raids and groups is way better way of judgement though.Weapon damage stacking in groups and raids is much more efficient and better scaling than what you get on strawman alone.
Anyway,also about feated EoX you can also choose to use it or not use it depending on the timing and your judgement but i don't understand not having it.Also lets assume you need to debuff and you don't have the instant inferno curse.Does it kill your dps ?No.
